Printer Error on Boot: 49.38.13 -- HP Color LaserJet CP5525

Solution

In my case, I ended up having to clear out the "active" firmware and have it pull a clean copy from it's backup. To do this you perform a "Partial Clean" from the preboot menu.

To access the preboot menu follow the instructions on the Service Manual.

Before doing this, be aware it will clear out networking/admin password/ service password/etc. The Printer will have to be re-setup as if from new for the most part.

After you're in the preboot menu, navigate to the "Administration" menu, then select "Partial Clean". Accept the confirmation dialog, then press the back button until you're at the root (top-level) menu. Select "Continue". The printer will now reinstall the firmware from it's backup.

After it finishes it's restore. Re-configure the device with TCP/IP settings, admin settings, and any other customizations you'd made to the printer.

Problem & Full Story

I discussed our issues with our CP5525 printer previously. Well after we had resolved that problem, we started getting a new, more catastrophic problem. About a week after fixing the previous error, the printer got a new error, 49.38.13. I say more catastrophic because this error comes up as soon as the printer finishes booting. The error gives says to power printer off/on, but doing so only causes the error to come up again and wastes 2 minutes of your time.

With the error, User's are unable to print, and you are unable to get to any settings through the panel on the printer or through the web interface. The only way to make changes is to get into the preboot menu during startup.

Things I tried that didn't work

• Disabled jet-direct (preboot menu)
• Selecting First-boot (preboot menu)
• Removing network cable during boot
• Removing power cable and holding power button to clear memory/capacitors (~30 seconds)
• This almost worked, it booted up and I was able to navigate around the menus for a little bit before the error popped up again.

What did end up working was doing a "partial clean" from the preboot menu (See Solution section above). It is important to make the distinction between the "Partial Clean" option and the "Full Clean" option. The Printer has two copies of the firmware installed, an active and a backup. The active copy holds all the settings you've configured on the device, where the backup is a clean image with all default settings. The partial clean removes the active and replaces it a copy of the backup. Functionally this should fix any firmware corruption, but it also resets the device to factory defaults.

The "Full Clean" option removes both the active and backup firmware images, leaving the device in an unbootable state. This is only used if the firmware you installed was corrupt (corrupt download, or something).

So, to be clear. Use the partial clean, not full clean.

Error When Printing: 49.4A.04 -- HP Color Laserjet Enterprise CP5525xh

Soultion

In my situation, installing the latest firmware fixed the problem, 2304061_439461 at time of writing. Various threads on HP's support site suggest the issue is a "rogue" print job; in less dumb terms, it's a print job the printer doesn't know how to handle. Updating the firmware have given the printer the ability to understand the jobs that were causing the problem.

There are several ways to go about doing a firmware upgrade. They can be done remotely via the web interface, or locally with a usb drive. If you're mad and have your printer internet connected, you can also tell it to download the update itself. Do make sure to read the "Read Me" for the update, however, because they sometimes do specify that the update cannot be applied with a given method because of errors. No idea why this is, you'd think the update process would be pretty much the same regardless of method of application, but you'll probably save yourself a headache or two if you double check before hand.

Either way, follow the instructions in the user/service guide.

CP5525 User Guide
CP5525 Service Manual

You can easily find these for other models by Googling "$model user guide" or "$model service manual" -- User guides will generally be on HP's site, service manuals are generally not. I like manualslib.com.

Important Note: I ran into another problem after firmware upgrade. I'm not sure the problem was because of the firmware upgrade, but be aware of it as a possibility. You can read about the additional problem and how I fixed it here.

Problem & Full Story

We've had numerous problems with our CP5525xh printer. It's only used by three or four people, but, at least recently, has been about 80% of our printer complaints. I can't blame all the issues on the printer itself, there's a fair bit of user error, but the thing is unreasonably unstable in general.

On recurring issue has been the printer crashing when we have the gall to try to make it print something. When this happens we get the 49.4A.04 error, and the printer must be rebooted to restore service. This will fix the printer, until the problem document is printed again.

The error is document specific, certain documents print fine, others cause the error. There doesn't seem to be much rhyme or reason to which documents it accepts or doesn't; other than that problem documents are often more complex documents (files printed from photoshop, lightroom, and some more complex .pdf files). Also interesting to note that documents that once print fine can have minor edits done, then stop working. The preeminent case was the adding of a text box to a poster one user was working on in photoshop causing the document to stop printing.

Worth noting also that this is strictly a printer issue. The job is spooled and sent through the print server without error. Same error also occurs when printing directly, rather than through a print server.

Some things we tried that didn't work

• Selecting "First Boot" from preboot menu
• Selecting "Cold Boot" from preboot menu
• Direct mapping printer, rather than using print server
• Rebooting User's machine / restarting offending program
• Reinstall / Update drivers on User's Machine
• Reinstall / Update drivers on Print Server

 Another option is to have the user export the document (to a more widely accepted format) before printing. This seems to work in most cases, but was met with much hostility as a work around (additional steps / time in workflow).

What finally fixed it for us was to install the latest firmware for the printer -- see "Solution" section at the top.

Samsung Galaxy Light - WiFi calling "called ended", WiFi messaging fails

Resolution

Update 9/24/14

Been using for a bit now, haven't had many problems. Still have an occasional call that goes straight to voice-mail or a text that won't send until you reboot, but the problem is much less pronounced than before, and doesn't have the same repeatability that it had before.

Writing this now because I just got a new firmware upgrade today. We'll see if it has any effect on the situation. That page says that it only enables "in flight texting", but it wouldn't surprise me if there were additional bugfixes included.

--------------------------------------- Original Text -----------------------------------------------------

In contrast to most of my posts, the solution to this is actually available pretty readily on the internet . I am posting this to confirm that it worked on my two phones, because people are pretty bad at updating forum posts once they've found a solution.

The fix in this case is to run a firmware update via the "Samsung Kies" software. This firmware update is not available OTA. Testing over a ~24 hour period I have been unable to reproduce the problem, which was quite easily reproduced before the update.

While researching this problem, I found many similar reports of other Galaxy phones (s3,s4,etc) having the same problem. None of those reports seemed to have a resolution, only the Galaxy Light thread had anyone confirm that they had fixed it. So, if you have another Galaxy phone with the same problem, I would check to see if there is a firmware update available via the Kies software.

Installing and running Kies software

1. Download the Kies software for your platform from Samsung's website
1. There are two versions "Kies" and "Kies 3". For the Galaxy Light, you want "Kies", newer phones may need the "Kies 3"
2. There is also a version for Mac, only one version though, not sure if that works for all phones or what.
2. Install the Kies software.
1. There isn't much to do here. Just click next a whole bunch really. Though I did opt to install the "universal drier tool", not sure if that's necessary. 
3. Open the Kies software, you should see a "connect your device" type prompt. Connect your device.
4. If this is the first time you've plugged in your phone to the computer it may take a few minutes to install drivers.
1. Note: I did have one of my phones lock up while connecting it to the computer (screen and hardware buttons became unresponsive). A Force reboot fixed it.
2. The device needs to be in MTP mode, not PTP mode. Kies will warn you if it's not. 
5. When I hooked up my phones, it immediately prompted me to do the firmware upgrade.  If this doesn't happen for you, the "Basic Information" tab should show the current firmware and whether or not it's up to date.
6. Follow Kies instructions to upgrade the firmware. 
1. The first time I ran this, I let the phone go to sleep while Kies downloaded the firmware update. Since the download took a while (I don't have super fast internet at home) the phone disconnected from Kies and I had to start the process all over again. Had to sit there swiping the screen back and forth while the download happened to keep it from sleeping/disconnecting.
7. Phone will reboot and install, don't turn it off or do anything to it while this happens.
1. The upgrade performed just fine for me on both phones, with no loss of data. Still, if you have critical stuff on your phone (why do you have critical stuff on your phone?, keep that stuff somewhere less steal-able) maybe back up the phone (can be done with Kies (Backup/Restore tab), or about 1000 other things) before doing the upgrade, just in case.

That's about it. Once the firmware update is complete you shouldn't have any more problems with WiFi Calls not dialing, not receiving calls on WiFi, or not being able to send/receive text messages on WiFi.

In interest of full documentation, One call I made right after the upgrade had really poor call quality (sounded like I was underwater). This was one call and have not had the problem reoccur since. 

The Problem / Full Story

We recently switched to T-mobile because they're reasonably cheap (for what you get) and their business model is slightly less troublesome than most big carriers. <Rant>took about 8 hours on the phone over 2 days to get the plan set up properly because the original guy who sold us the plan didn't know what he was doing </Rant> . Anyway we brought our devices, because you can pick up the Galaxy Light on Amazon for dirt cheap.  It's not a high-end phone, but it's a reasonable spec with a fairly recent version of android (4.2.2). 

But enough advertising, you wouldn't be here if you weren't having a problem. The phones worked fine for a few days, but we started having problems with the WiFi calling within about a week. WiFi calling was a big deal for us because all carriers (besides Verizon, but fuck them) have not-so-great coverage in my town, but we have WiFi pretty much everywhere we go. So problems with the WiFi calling was problems with our service in general.

Problems were as follows. If the phone was allowed to sleep for awhile (seemed to be 30-45 minutes on average) WiFi calling would stop working. This means, with out a cell signal (which I don't get at work because my building is made out of concrete and florescent lighting) no calls could be made or received and no texts could be sent or received. Not that the phone was aware of this, the WiFi calling icon in the notification bar was still blue and it said it was making calls over WiFi. When you actually tried to place a call, however, it would immediately end the call (at 0:00 seconds) and call status would be "Call Ended". Looking at call history you would see "Canceled". Trying to send Texts would result in a "Failed to Send" message. People trying to call us would get send straight to voicemail, or occasionally one ring then voicemail. Then only way to restore service was to turn WiFi calling off-and-on (usually) or reboot the phone. This fix would only last until the phone went into some low sleep state (seemed to be ~30 min of screen off).

After much internet searching and playing around with settings on the phone I came across this thread (also linked at top) about the WiFi calling on the Galaxy Light. A non-OTA firmware upgrade was available and fixed the problem (see above for steps).

Here's some things I tried that did not work

1. Clearing data (via application manager) from "WfcService" and "Wi-Fi Calling Settings"
2. Changing Wi-Fi calling preferences (prefer cell, etc.)
3. Different Wi-Fi networks
4. Standing close to router (router is on my desk at home, so while sitting at desk phone is <5 feet from router)
5. Turning off voice control
6. Turning off other wireless radios (bluetooth, gps, NFC, etc.) 

Here's some other things I've seen reports of people trying that have not worked

1. New phone - This appears to be a problem with at least all Galaxy phones. Seen reports of people getting phones replaced 4 or more times without resolution. 
2. Factory Reset
3. Changing network mode (LTE/WCDMA/GSM, WCDMA/GSM, WCDMA only, GSM only)
4. Changing Sim cards/upgrading sim cards
5. opening ports on router
