HP LaserJet 4600 Printer Questions & Answers
HP 4600 print cartridges won't pull out. Seems like something has locked them in. Any suggestions?
Hello Mitch,
The problem with the HP laserjet 4600 (cartridges won't release to be removed) is that the plastic cartridge lock lever located on the right side has broken and will not release any cartridge at all unless the side is taken off and you can move the lever by hand. This cheap plastic locking arm does all 4 cartridges at once.It is not exactly an easy fix and is very patience testing! Your printer needs to have a tech replace this locking mechanism.
Good Luck!

Error code EI0 1
EIO 1 is the port in the back of the printer for a JetDirect Network Card, or for the External Hard drive.
Pull the card out of the slot (turn off the power first) then turn on the printer to see if the error went away. If so, you need to replace the item you removed.
Hp color laser jet 4600 57.40 error
57 indicates a printer fan error has occurred
the .4 points to the formatter fan (F1) is bad.
Connector J1004. Voltage should be 24 VDC between pins 1 & 3.
If it is, then replace the fan, if it isn't, replace the DC Controller PCB.
Why do I get 3 groans during calibration accompanied by a 51.2m error ?
51.2 is a laser error.
there should be another number after the 2,
0 = black laser
1 = cyan laser
2 = magenta laser
3 = yellow laser.
The groan is most likely the polygon motor has lost its lubrication and may just need to be cleaned and re-lubricated.
You can also try reseating the connectors from the lasers to the DC controller PCB...
Error 49.4c02
Disconnect any network or usb cables from printer and try to restart. If printer will restart and comes to ready you need to update the firmware. If you still get the error then either the memory on the formatter is bad, the firmware on the formatter is bad or the formatter itself is bad.

Replace the black laser assembly !
Reset ink levels
For resetting the toner levels, cartridge memory chip has to be replaced. Memory chip was mounted beside of the each cartridge & its easy available in the local market.. For better idea pl see the snap..
Printing only symbols and numbers
The two most typical causes for this type of behaviour are:
1. wrong print driver being used. Ensure that you are either using the proper HP print driver for the 4600 or the HP Universal Print driver.
2. Bad communication cable, loose connectors or dirty connectors.
Try printing the configuration page from the control panel. If that prints ok then it is more likely the two above causes. If the configuration page prints wrong then you probalby have a formatter issue or memory issue.
To print the configuration page, press the down arrow until it reads information, press the check mark, then use the down arrow until configuration page shows then press the check mark again.
