Disable Carts is for service tech troubleshooting.

You will have to replace. All prints use all cartriges every time.

SOURCE: I have HP laserjet M2727nf

Your unit is displaying a common formatter failure. The good news is this:

Any HP M2727 manufactured before January 1, 2010 is covered by a service advisory that will get the printer repaired at no charge. You need to contact HP and get a case number or contact an authorized HP service partner. Be insistent, I have seen some service partners who have no idea that this service advisory exists. You can check the date of manufacture by looking at the serial number sticker on the back of the unit.

SOURCE: We have a service agreement

The following procedure is used to initiate the Service Mode.
1 Hold down the [Menu+] and [Value+] keys while powering ON the printer. Hold the keys down until SERVICE MODE is displayed.
2 The interrupted power-on self test is resumed. If the test completes successfully, the message SERVICE MODE is displayed.


1 Enter the Service Mode as described previously.
2 When SERVICE MODE is displayed, press the [MENU] key to access the Service Menu. Press the [ITEM] key to step through the menu.
3 PAGES=XXXXXX is displayed. XXXXXX represents the page count currently stored in the printer's NVRAM. The underlined character denotes the cursor position.
