Description
The device could not print the current page because of its complexity.

Recommended action
Press ENTER to clear the message.
Allow the device to finish the job, or press CANCEL to cancel the job.
Lower the USB speed on the product by turning off "High Speed USB". Following are instructions on how to do this from the Secondary Service Menu:
To access the Secondary Service Menu press the Menu button.
Now press the #2 button and use the < arrow to navigate to the High Speed USB selection.
Press Enter and then use the arrow key to go to Off and press Enter again.

We would like to inform you that the error you are getting is not because of the printer driver installed on your computer but due to the USB speed setting on the computer.



. Please perform the following steps on the printers control panel.

a) Press the Menu button.
b) Press 2 on your keypad and then you will see Secondary Service/Service Reports.
c) Press the right arrow button until High Speed USB appears.
d) Press the Enter button.
e) Press the right arrow button until OFF appears.
f) Press the Enter button.

Print something from the computer to test for the issue.
The first print after performing the steps will take a little time to print but the remaining page will print in the normal speed.

Selection to turn off high speed USB clears out the memory and next print jobs works better, because the memory is no longer fragmented.

3. If the error persists, please perform the below steps:

NOTE: If possible, print a configuration page and menu map prior to performing a cold reset.
This will document the current settings for later reference as performing factory default settings will clear all the information stored in the printer.

Perform the following steps to restore the factory defaults using the device control panel.

a) Press the Menu button on the device control panel.
b) Use the < (Left Arrow) or > (Right Arrow) button to select Service, and then press the Enter button.
c) Use the < (Left Arrow) or > (Right Arrow) button to select Restore Defaults, and then press the Enter button. The device setting will revert back to the factory default settings and the device will restart.

SOURCE: 2840 only prints on right side

If you are a bit adventurous and a bit patient, you perhaps can fix this yourself, and not require any disassembling. It worked for me on a similar 'carousel' unit... hp2550L.

For extra info, check this post out. http://www . fixyourownprinter . com/forums/laser/40284 (remove spaces)

If you look closely at the spot where a toner cartridge slips into a slot of sorts, you might see left side aligned and right side just a little off of 'good alignment' for that slot. What I did is to pull on the top of the black-plastic gear. Pull it toward the center of the printer.

There is a small, white gear at the very top of the black gear (not easy to see at first). By this pulling and bending of the black-plastic gear, you can get the gear teeth free of the white gear --- for just a moment. Just enough for the gear teeth to free-up and find their proper place. It doesn't take much.

When done, take a breadth and relax. Turn power off/on, and try it out.

MY HP LaserJet 2840 has a brand new Toner cartridge. Now it won't print at all and we are getting a "OPC at end of life" prompt. What does this mean?


Imaging drum reach 20,000 (black only) or 5,000 (color), replace the image drum.

Supplies life
The life of the imaging drum depends on the number of black-only or color pages that print jobs
require. Imaging-drum life is also affected each time the device calibrates because calibrating causes the imaging drum to rotate. Imaging-drum life is measured in terms of number of rotations rather than number of pages printed.
The type and length of print jobs also affects drum life. A series of short print jobs uses more drum
life than an equivalent number of pages printed in a single large job. To extend drum life, print
multiple copies of a print job at one time rather than sending the same job to the device multiple times.
The life of a print cartridge depends on the amount of toner that print jobs require. When printing text at 5% coverage, black print cartridges last an average of 5,000 pages and cyan, magenta, and
yellow print cartridges last an average of 2,000 pages. High-capacity cyan, magenta, and yellow print cartridges last an average of 4,000 pages. (A typical business letter has 5% coverage.)

The HP Color Laserjet 2840 Is a Very Good Reliable Printer. I'm curious if you are buying American made components or cheap components from some thrid world country sold at ahuge retailer. They really should stand behind their laser drums, but if they don't then shop over at www.officeinks.com or www.wowsuperdeal.com and Purchase American Made Toner Cartridges and Laser Drums. Office Inks has a 1 year satisfaction and quality guarantee and free return shipping if their ink, toner, drums, ribbons etc, don't make you happy. Only Ships USA Though.

Replaced black toner..now printer won't print any


In this case, actually it is not the Black toner that got depleted. Here the message being displayed indicate that one of the color Toner supply need to be replaced as it got depleted and currently the printer is printing in Black and white using the Black toner cartridge.

in this case, to troubleshoot these issues please try performing the following and check for the results.

* 1. Check for the level of the toner cartridges:

a) Check from the HP Toolbox application. Here are the steps to be performed from your PC:

* Access the Toolbox software.
* Select the Status tab.
* Select the Device status option.

Here you can check for the supplies status in terms of the % remaining for each toner cartridges.

b) By checking the supplies status from the printer control panel display.

On the printer display when printer is in Ready mode the supplies status can be checked from the supplies level indicator. Each toner cartridge and the Imaging drum level will be indicated by a bar which varies according to the level of the supplies present.

c) Print the supplies status page from the printer.

* On the printer control panel menu, press Menu .
* Use the (Right Arrow) button to select Reports, and then press Enter .
* Use the (Right Arrow) button to select Supplies Status, and then press Enter .

If any of the color toner cartridges and the Imaging drum have a low supply level replace them with genuine HP print cartridges.

The part numbers of the consumables are as follows:

* Black print cartridge - Q3960A
* Cyan print cartridge - Q3971A
* Magenta print cartridge - Q3973A
* Yellow print cartridge - Q3972A
* Imaging Drum - Q3964A

HP 2840, black ink drum q3964a


Hello, these printers tend to be finicky.

In other words, just replace the black toner. When the printer says its low, or empty, regardless of wether or not it is, just replace it.

Replacing the drum, when it says black toner needs to be replaced will do nothing to rectify the issue.

Buy only HP Toner and Drum cartridges for this printer. Do not try to refill toner cartridges, and do not reset drum. You will only end up destroying your printer in the process.

Replace Cathridge


The front panel tells you witch toner cartridge should you replace. If a supply memory error ocures then the cartridge should be replaced or exchanged with a new one. The imaging drum unit is also consumable. for "Joe 50" - there are 4 toner cartridges in the printer.

HP 2840


the carousel gears are out of sync - "off a tooth" and have to be realigned.  i spent 3 days last week fixing this problem - it's quite a job, to say the least.  my question - if you ever check for this answer - is: what were the circumstances when the problem first occurred?  just after replacing a toner cartridge?  if so, was it recycled cartridge?
