I had an issue similar to this and it was fixed by replacing the memory dimm on the bottom of the formatter.

Well we can check and see if the printer is able to run an engine test. This is how you can run this test;

  1. Turn the printer around so the back of the machine is facing you.
  2. Remove the Engine etest button acess door. This is located in the bottom center of the back.
  3. Push the botton once while the printer is on. The printer should print a page with colored horizontal lines.
If the printer is able to print this page there is a very good indication the problem revolves around the PCA formatter board.
The Firmware might be outdated and causing this problem. Worst case scenario the board might be faulty, in that case your better off buying a new machine, since the cost to replace the board will be higher than that to replace this machine.

The device has experienced an internal hardware error. Recommended Action

  1. Turn off the power by using the power switch, wait at least 30 seconds, and then turn on the power and wait for the device to initialize.
  2. If the error is still unresolved, contact Hewlett-Packard for technical support to troubleshoot the problem. Call HP for telephone support

SOURCE: Hp 4300 laserjet. All printouts have a blank space

Remove the toner and wipe the small window that's above where the drum unit sits inside. That window gets covered with toner and makes light prints and blank areas.

SOURCE: HP laserjet 5550 not printing cycan. Replaced

You will not find the answer to this problem on any forum as I have searched each one! However I have had the same problem and found out that if you have reseantly replaced or reseated the Paper Pic-up assy you may have not pushed down the plastic top cover which sits directly underneath the Cyan Cartridge, this will cause your 5550/5500 to think there is no problem and carry on printing without any error messages.
I'm just a man doing a boys job, lol

Testimonial: "Wow! Thank you sir. That was the problem. I had not touched the paper input assembly. So obviously, a user did this. Thanks again!"

Initializing scanner hp cm6040


Most common cause of the error on this printer is the memory on the CPB (copy processing board) is bad. This board is picky about memory and typically only works with the actual HP memory designed for it. The easiest fix is to use the memory that is currently installed on the formatter, which is identical, and purchase 3rd party memory for the formatter, which will support any compatible memory.

HP CM1312 DISPLAY DEAD, READY LIGHT SOLID, EXCLAMATION POINT SOLID


I hope its formatter(mother board) faulty,remove USB cable, un install the drivers from the system, found new hard after connecting the printer? if its not recognizing replace formatter assm..or else display panel..Hints while repairing: Flat cable is too short between scanner assm & DC controller, before powering on verify this cable properly fit or not.. While opening the printer side covers by mistake flat cables of ADF & display plug off due to over length, if we are not concentrate on this it will damages the formatter,if we gives power(might be this issue raised in your printer)..Never disturb/remove the laser scanner assm.. it will kill your patience.Never try to remove laser scanner assm with out cartridge bank( for repair normally we will remove this bank), it will fall down on ETB.. verify all connector properly fixed or not before powering on..

Hp lazer jet 2600N won't print red color what will fix it. Has a new cartridge


You may need to replace FORMATTER BOARD & DC CONTROLER BOARD ASSY which are located behind the printer. Both BOARDs are side by side together. Just open the back cover, you will see it.
