HP LaserJet 4100 - 68.0 PERM STORE WRITE FAILED

68.0 PERM STORE WRITE FAILED on a Hewlett Packard LaserJet 4100 can be repaired without replacing the formatter board. This error isn't mentioned in the service handbook or on the HP website.

The closest to this, with the solution is:

68.X Permanent Storage Error (Check Settings)

Explanation

An error occurred in the printer’s permanent storage and one or more printer settings has been reset to its factory default.

Recommended action

Print a configuration page and check the printer settings to determine which values have changed.

68.X Permanent Storage Full

Explanation

The printer’s permanent storage is full. Some settings might have been reset to the factory defaults.

Recommended action

1. Print a configuration page and check the printer settings to determine which values have changed.

2. Hold down CANCEL JOB while turning the printer on. This will clean up the permanent storage by removing old areas that are not being used.

Because this isn't the precise error, it probably won't clear the fault and you would end up replacing the formatter board.

Instead, this is what you need to do.

Firstly, try cleaning up the NVRAM as suggested on the HP website by turning the printer on while holding down the CANCEL JOB button until it says CLEANUP NVRAM on the display and then release the CANCEL JOB button.

If you still get the error, press GO to continue and then print out the configuration settings and menu settings. You then need to do a NVRAM Initialization. Before you do the NVRAM Initialization, remove any network cards, accessories, and DIMMs from the formatter that did not come with the printer.

Next, turn on the printer while holding down the SELECT and CANCEL JOB buttons until all the LEDs stay on. Release the two buttons and then press and release the CANCEL JOB button and then the SELECT button. You should then see NVRAM INIT on the display.

If you still get the error after doing the NVRAM INIT, do the NVRAM cleanup once more as described previously, that did it for me.

You will then need to enter your menu settings and then go into service mode to enter the page counts, default paper size, and any other settings that have changed.

SERVICE MODE

1 While turning on the printer, hold down SELECT snd CANCEL JOB until all of the lights on the control panel are lit

2 Press the right side of MENU, and then press SELECT. The message SERVICE MODE temporarily appears and will reappear when the printer completes the initialization process.

3 To ext Service mode, press GO.

Note if READY appears on the control panel, the buttons might have been released too soon, or the wrong buttons were pressed.

HP Color LaserJet 2500 - Attention Light Flashes After Every Page

If your Hewlett Packard Color LaserJet 2500 Attention light flashes after every page and you have to press the Go button to continue, you need to check the size of the paper in the paper tray and the size of the paper set in the printer properties.

If these are the same, print out a config page by pressing the Go and Cancel buttons together. Look for the Default Paper Size in the bottom right of the first page.

What you might find is that the paper in the paper tray is A4 and the software is set for A4, but the printer has defaulted to Letter size.

In normal use, this won't happen or you probably won't notice it. You're more likely to come across this in a workshop enviroment while repairing and testing the printer. You will see it when you print a test page or config page.

Two possible causes of this are:

1. You've replaced the formatter board and the paper size is set to the factory default Letter.
2. You've performed an NVRAM INIT on the printer which has set the paper size to the factory default Letter.

 There's two ways to fix this. If you've got the original CD that's shipped with the printer, there's a utility on it to set the default paper size.

If you've not got this CD, you need to send a file to the printer to set the default paper size. This is the contents of the file with comments to explain what each line does:

←%-12345X@PJL    Start PJL job
@PJL SET SERVICEMODE=HPBOISEID    Enter Service mode
@PJL SET CRPAPER=A4    Set cold reset page size [=Letter/A4]
@PJL SET SERVICEMODE=EXIT Exit Service mode
@PJL RESET    Perform PJL Reset
←%-12345X    Exit PJL mode

The left arrow ← at the start of the first and last lines represents the Escape character. If you create this file using MS-DOS Edit, you enter the Escape character by holding down CTRL-P and pressing Esc. This will look like a left facing arrow, ←, on the screen.

There's a good chance you're not running a Windows 98 / MS-DOS machine with MS-DOS Edit. Whatever operating system you're using, you will need to create a plain text file. You will also have to consult the documentation for the editor you're using to see how to insert the Escape character.

Once you've created the text file, save it with any name you like but give it the pjl extension, e.g. A4.PJL. You then send this file to the printer. If you can go to an MS-DOS command line, the following will work if you are connected to the parallel port of the printer:

type a4.pjl > prn

The green light will flash for a few seconds and then the printer should go into the ready state. Print out a config page and check that the default paper size is now set to A4.

For your convenience, I've created A4.PJL for you which you can download by clicking the following link:

A4.PJL 

The escape characters will look like squares if you open this file in Windows XP Notepad.
