P2015: Strange Error Lights

Personal LaserJet printers have typically relied upon a trio of lights to communicate printer states and error conditions. The LaserJet P2015 has the three basic lights and three additional lights that correspond to specific low-level error conditions (The new lights are circled in Plate D).

The manual does not tell us what to do if more than one of these new lights activates (Toner Low and Paper Jam is the most common combination). Liberty Parts Team has determined that a bad formatter is more likely to cause this than simultaneous error conditions.

The easy way to distinguish between a bad formatter and a real case of multiple low-level errors is to run an engine test. As with other LaserJets, the engine test exercises all parts of the printer except the formatter. If the test print is successful, everything aside from the formatter is shown to be working.

To run the engine test on the P2015, follow these simple instructions.

  1. Open the Print Cartridge Door.
  2. Remove the Lower Left Cover. At the rear of the printer, use a flat-blade screwdriver to release the upper (Plate A) then the lower (Plate B) tabs, and lift the cover away from the printer. Plate C shows the tabs.
  3. The engine test button is accessed through a hole in the frame just below the right lower corner of the formatter (Plate E). With the printer powered on and paper loaded in the tray, press this button with a small screwdriver to print the test. The engine test sheet consists of a single page of closely-spaced lines.

If the test print is successful, the formatter caused the error. If the lights occur again, you have actual simultaneous errors.

There are two versions of the formatter:

  • Q7805 (with an embedded network port)
  • Q7804 (the non-network version)
