HP — Engine cleaning

Engine cleaning Note For best results, use a transparency during this process. If a transparency is not available, use copier- grade paper; do not use bond or rough paper. This process uses a transparency from tray 1 to remove dust and toner from the paper path. Use this process if toner specks or dots appear on printouts. This process will produce a blank page which should be discarded. Figure 32. Print sample Note During the engine cleaning process, the printer pulls the transparency into the printer and then stops. This is not a jam. The transparency will be slowly stepped through the printer to complete the engine cleaning.

To start engine cleaning Step 1 Make sure the printer is turned on and in the ready state. Load a transparency in tray 1. Step 2 Press and hold 10 seconds. Step 3 Release G O , the lights will cycle from front to back until the cleaning process has completed. Note If G O is not held long enough the device will print a demo page rather than performing the cleaning process. Step 4 Discard the blank page produced from the engine cleaning process. 64 Chapter 4 Printer maintenance C7058-90936
