I have all new Q39**A series cartridages in my 2840 but the printer wll not recognize them and will not print in color. When I replace the Q3972A with a new Q3962A it recognizes the cartridge and tells me to replace the other two Q39 series cartridges. Is there a fix for this so I will not have to purchase new Q3962 cartridges and waste my money use to purchase the Q3972 series ones?

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.)

It seems that the connectivity b/w the printer and the computer is not through. Is it a wired or wireless printer? When you switched to comcast, did you made any changes to the wired connection with printer?

Hi there

Did you do a reset in the Menu or on the printer when you replaced the new drum.
All best Pineworks

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

Black is used on all prints. Did you pull the tape on the new cartridge?

If one of the color cartridges runs out the machine will switch to black only mode. However, I have found no way to force it to continue printing in color mode when any one of the cartridges runs out.
