Paper Preheater Cleaning (Remove Print Smears) The paper preheater cleaning procedure is a function selected on the control panel by the user. This procedure cleans ink out of the paper preheater that may have been deposited there. Heavier-weight, high-grade quality paper works best for this procedure. Ink can also be deposited if a jammed print, with ink on it, was pulled backwards through the paper preheater. To perform the paper preheater cleaning cycle: 1. On the control panel, select the Print Quality Problems menu and the Remove Print Smears menu. 2. The system overheats the paper preheater to about 100o C, softening ink trapped inside the paper preheater. Ordinarily the paper preheater runs at temperatures of between 60o C and 65o C for paper or transparency film printing. 3. The system picks and passes approximately 12-24 sheets of paper through the paper path. The first few sheets absorb and remove ink from the paper preheater. The system continues to pass sheets of paper though to cool the preheater until normal operating temperature is reached. If duplex capability is enabled, 5 sheets of paper go through the simplex paper path and up to 20 sheets go through the duplex paper path. 4. The system returns to the Print Quality Problems menu. Because of the higher paper temperatures involved, this function can also be used to clean the drum surface of ink deposits caused by a contaminated blade on the drum maintenance system. Transfix Roller Oiling Oiling the transfix roller prevents ink from sticking to it. Every 50 prints, the system performs a transfix roller oiling cycle. During this cycle, oil is applied to the drum as it would be during a print cycle. The transfix roller is lowered against the drum and the drum rotates, which transfers some of the oil to the transfix roller. The transfix roller is then raised to its standby position. Drum Cleaning - Chase Page The system performs a drum cleaning with a chase page automatically anytime a paper jam occurs. The chase page transfers any image, which may not be complete, off the drum. The system then attempts to reprint the print that jammed. The chase page is processed the same as a regular print, except that the drum is not oiled and no image is printed on the drum (since an image is already printed on the drum). A chase page is also run during startup/recovery if the system believes that there is ink on the drum. 7-4 WorkCentre C2424 Service Manual
