Image Quality RAPs
IQ5 Print Damage RAP
Use this RAP when the prints have nicks, tears, creases, folds, curled edges or wrinkles.
Ensure IQ1 Image Quality Entry RAP is performed before starting this RAP.
Procedure
Enter Diagnostics, GP 1. Enter dC606. Select the internal test pattern 14. Make prints to iden-
tify where the prints are damaged.
Check the paper path, Figure 2 for the following:
• Obstructions.
• Damaged guides and rolls, GP 7. Pay particular attention to the areas that align with the
damage on the prints. For example, fuser stripper fingers.
• The edges of the paper path for protruding objects.
• Ensure that the paper feed does not skew the paper, go to the appropriate procedure:
– 08-101 Tray 1 Misfeed RAP
– 08-102 Tray 2 Misfeed RAP
– 08-103, 08-113 Tray 3 Misfeed RAP
– 08-104, 08-114 Tray 4 Misfeed RAP
– 08-115B, 08-117B Tray 5 Misfeed RAP
• Check that the paper strips from the xerographic module and enters the fuser nip cor-
rectly. If necessary, perform the following:
– If the paper does not correctly strip from the xerographic module, ensure that all the
HT leads on the HVPS PWB are correctly connected, refer to REP 1.1.
– If the paper is contacting the upper fuser roll before entering the fuser roll nip, check
that the short paper path is correctly latched and the transfer/ detack corotron, (32-
38 ppm) PL 9.22 Item 8 or (45-87 ppm) PL 9.20 Item 2, is correctly positioned, ADJ
9.1 Corotron Cleaning.
• Check that the fuser roll stripper fingers are clean.
• If the prints are creased or wrinkled after the fuser module, then install a new fuser mod-
ule, (32-55 ppm) PL 10.8 Item 1 or (65-87 ppm) PL 10.10 Item 1.
• Ensure that paper path sensor actuators move freely, GP 7.
• If the paper is corrugated after passing through the fuser module, install a new tri-roll shaft
assembly, PL 10.12 Item 8.
• If the paper is curled after passing through the fuser module, go to Curl Measurement.
• Check the inverter for damage or wear, GP 7.
• Check the duplex transport for damage or wear and the jam clearance latch is located
correctly.
• Check that the output device is not position near a air conditioning or ventilation output
ducts. Air blown across the output bins can cause poor stacking.
• To check the paper path without an output device, use the finisher bypass harness, PL
26.10 Item 7, to check the paper path through the inverter complete assembly, PL 10.11
Item 23.
If the paper path and the duplex path are good, check that the paper and other media used, is
of the correct weight and size, GP 20.
Curl Measurement
Make five singled sided prints. Refer to Figure 1. If the curl on the print exceeds 13mm. (0.5
inch), perform the following checks., go to IQ4 Fuser Module RAP.
• Check the paper storage and wrapping.
• Turn the paper stack in the paper tray over.
• Use paper from a new ream.
• Go to IQ4 fuser Module RAP.
Figure 1 Curl height measurement
Place the print on a flat surface. Measure the curl within 5 seconds.
Maximum allowable curl for any paper size in any direction: 13mm (0.5inch)
