When printing, the printer makes a loud sound

I just replaced the imaging drum and after a few days, every time I a print a document, our HP 2840 will print it however, it makes a loud noise during the printing process. It sounds like trying to start a car and the battery or alternator is not functioning. Can you assist me as what is causing this noise???

I first guess that it is the drum going out. If you have changed the drum......it is more than likely your fuser. Have you ran a supply check to get the status on your supplies?

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.)

Laser printers work by creating latent images on a rotating, light-sensitive drum and then attracting toner to exposed points on that drum. If any point on the drum’s light-sensitive surface is damaged, you may notice that toner is always attracted to that point, thereby transferring to the final page and appearing as a repeating mark. Because the drum is a cylinder, such marks will appear at equal distances down the page, corresponding to each rotation of the drum (maybe every two inches, for example).

The only solution to this problem is to replace the drum. For most low-cost home printers, the drum is part of the toner assembly and is automatically replaced each time you install a new toner cartridge (which explains part of the cartridge’s high cost). More industrial-strength laser printers place the drum on a separate EP (electrophotographic) “engine” that can be replaced in just a few easy steps. Check your printer’s documentation and replace the appropriate assembly (or have someone do it for you), and the repeating marks should go away.

We just replaced the imaging drum on our HP 2840. Now when we print in color, we get the image we printed, plus a lighter version of the same image about 2.25 inches lower on the page, every 2.25 inches. ...


A repetitive defect at that spacing points to the transfer roller. This is the roller in the bottom of the drum/cartridge cavity. Most likely you will need to aquire a Q3948-67920 transfer roller kit.

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

HP Color Laserjet 2840 now makes ear-splitting whine every time


Did the noise start right after you replaced a toner? If so it must be a bad toner which is causing the gears to grind. If this noise happened out of the blue then it might be a bad fuser drive gear which is the gears that connect the fuser to the machine.

Not printing on left side of page


The problem is that the revolving drum doesn't contact the OPC drum proberly. You have to open the left side off the machine and replace the little white gear on the shaft that drive revolving drum. The gear has "jumped"one step and the revolving drum isn't parallell to the OPC drum. I fixed my 2840 last night it takes some time but now it works perfect.

You will need to replace the image drum. This is either due to the face that you have exceeded the number of pages/cycles that the drum supports or the drum has damage. If this is the drum that came with the printer, it is likely they shipped it with "starter" supplies which last a fraction of the time as the regular "full retail" replacement supplies. A URL for HP's instructions on how to replace tn image drum on the HPCLJ 2550 series follows:
