This is very much like a corupt driver issue I have seen on hundreds of machines and the same problem we get in our tech support call center on a daily basis.  Often a Windows update will not block the driver signal, but it will obscure it. 

The teltale sign is very slow printing.  Often taking 1 to 3+ minutes per page (especially if the document is complex).  Completely wipe out the driver, download the full HP driver set, then re-install.  I often advise users to use a different IP address.  Maybe alter the last octet by 1 digit. 

Hope this helps.

Unfortunately, this issue also occurs when printing internal print jobs. There are long delays during printing from within the printer (with no driver). Looking at the error log there seem to b several 54.1e.0a and 54.06.07 errors.

Hi,

Oh... That is a different kind of mess. I thought you were getting spooling delays. They are very common in this unit because of the complexity of the drivers for it and because Windows updates plays heck with them. You can also uncheck the box that says, "Let Windows manage my printers".  That helps un-disaster them on many occasions.

But for the errors, are you using OEM toner?  The 54.06.07 error is your cyan toner sensor having a bit of a nervous breakdown.  The 54.1e.oa says that the black density sensor is also freaking out. 

And this is happening on multiple units?  They are rare enough for one unit to have this problem, but for multiple units, there has to be a common demonator with them. 

What is one thing that was done to (or happened to) every unit having this issue?   Toner leak?  Generic toner?  Refilled toner?   I always tell our sales reps to push only OEM for the color HP units.  It saves a lot of grief in the long run.

Hopefully it is just a toner incident that caused it because it really is beyond rare for multiple units to have this problem.  If you have these issues with all your units and you are using OEM, then contact HP and ask for an incident escalation.  If they are out of warranty, I would still ask for some kind of help, even if just advice.

smartin2662,

54.* errors

Errors in the 54.* family are related to the image-formation system.

• For HP LaserJet printers, they can indicate a problem with the toner cartridges or the transfer unit (color printers only), or they can indicate a problem with a sensor, such as with the laser/scanner.

Recommended action for LaserJets

Use the following general troubleshooting steps to try to resolve the problem. If the error persists, elevate the case using the Standard Support Process.

1. Turn the printer off, and then on.
2. Check the supplies status page to verify that toner cartridges or the transfer kit are not past their useful life. Replace supplies as necessary.
3. For color printers, inspect the transfer belt for damage, and replace it if necessary.
4. For color printers, if the error persists, replace the registration assembly.
5. Check the connections between the laser/scanner and the DC controller, and from the laser/scanner to the printer. Reseat them if necessary. If the error persists, replace the laser/scanner.

I hope this may help you with the errors,

Cheers!

So, I installed a new set of HP toners into one of these printers. I replaced them one at a time and printing out an event log after each new calibration. I do not see any of the 54.06.07 nor 54.1e.0a erros that I noted in my prior posts. However, I see errors:

54.0c.00

54.0c.01

54.0c.02

54.0c.03

Calibration error consecutive DmaxDhalf

on the event log after each new calibration.

What do these errors point to. Searching the web it seems possibly points to the laser scanners?

Hi smartin2662,

Does your printer now print ok?

Below you can see these error codes:

54.0C.00, 54.0C.01, 54.0C.02, 54.0C.03

Halftone Calibration Error.

54.0C.00 - Halftone Calibration Error for Black

54.0C.01 - Halftone Calibration Error for Cyan

54.0C.02 - Halftone Calibration Error for Magenta

54.0C.03 - Halftone Calibration Error for Yellow

  note:

This error is not shown on the control panel, and is only an informational error posted via the Event Log.

This error is informational only. It will not display on the control panel as an error, nor stop the operation of the printer. It is only recorded in the Event Log.

1. Ensure genuine HP Supplies are being use.
2. Check if toner cartridge is Low or Empty. Replace the toner cartridge if necessary.
3. Remove and reseat appropriate toner cartridge based off of the last digit of the error code.
   00 = Black

   01 = Cyan

   02 = Magenta

   03 = Yellow
4. Remove and reseat the ITB.
5. Open and then close the front door five (5) times, to clean the calibration sensors.
6. Perform a Quick and/or Full Calibration.
   1. On the control panel, ensure printer is READY , then Select the following:
      Device Maintenance

      Calibration/Cleaning
   2. Select: Quick Calibration or Full Calibration . (do this 3 times in a row)

I hope this will help,

Cheers!

Are you using OEM, Remanufactured or Generic toners?  If reman or generic, the toner will not as many functions have/offer as the OEMs.  Plus, they often internally fight the calibration. 

Like half-toning (which is what your error points to) is similar to the "photo ret" of ink printers where the unit can intermix different color toner on the same "dot" coordinates.  Generics and remans cannot do this.

If they are OEM and not calibrating, you could have a bad or dirty sensor.  These units are pretty robust, but they are just picky about the toner.  Kind of like a vegan forced to eat a large T-bone steak.  They don't do well later on.

I did what you sent as a suggestion for this problem and it seemed to have worked. After completing the sequence I again printed out all of the internal prints. I then printed out an error log...no new errors were listed.

I will continue to test this printer before returning it to the customer but you have given me great information when I look into all of the other M680s that are acting similarly.

Thank you very much.

[smartin2662]

Well, I retested this printer today. It seemed to print config page, supplie status page...etc. well. However, I ran a paper path test of 50 prints. It is back to printing as it was when this entire issue began.  The printer prints 4 pages continues to cycle for a bit, prints another 3 pages, cycles, prints 1 page, cycles, 1 page...etc.

I checked the error log...no new errors.

Since the start of this issue.

Frimware has ben upgraded.

Formatter replaced.

Hard Drive replaced by a sold state memory chip.

DC Controller replaced.

Printer was cleaned entirely.

Density sensor was replaced.

OEM cartridges were installed.

Now/still, an internal paper path test of 50 prints takes approximately 5 minutes to print out.

Any suggetions at this point??

[GaryL1]

Well, you have exhausted everything I can think of and even replaced way more than an average tech would have without being super mad at HP. 

One of the only things I can think of is having the resolution set to ImageRET 2400.  That slows down the prints.  And, please forgive me if the M680 calls it something different, but it is the max resolution the unit can kick out.

How fast does an engine-only test take to spool up?   Is it immediate? 

I have seen weak fusers cause pausing between prints because the fuser drops below operational temp and takes a few seconds to heat back up.  Is the fuser still spinning when it goes into the pause period?  That is one of the telltale signs of the fuser not being hot enough.

My experience is on the A3 MPS stuff, so I am not sure on this one:  The control panels on the larger units actually have their own operating systems.  These OSs control the path checks, test prints, etc.  If it is similar with that unit, you may have an issue with the onboard OS in the control panel?

Is this a "Flow unit"?

I'll answer when I can as it is busy in my office today.
