6/02 3-11 DC1632/2240 IQ9, IQ12Image Quality Prelaunch Training/ReviewCheck the components in the Registration Transport Assembly (PL 2.6) for wear, slipping, damage, or contamination. Clean/replace as required The defect occurred on copies from all five paper trays. YN Check the components in the Registration Transport Assembly (PL 2.6) for wear, slipping, damage, or contamination. Clean/replace as required Check the IOT Lead Edge/Side Edge Registration (ADJ 9.9) for that tray. Check the feeder for the affected tray for wear, slipping, damage, or contamination. ï Tray 1 Feeder (PL 2.4) ï Tray 2 Feeder (PL 16.7) ï Tray 3 Feeder (PL 16.9) ï Tray 4 Feeder (PL 16.11) ï Tray 5 Feed Assembly (PL 2.14) TBD. IQ12 Process Direction Bands, Streaks, and Smears RAPProcedureNOTE: The repetition rate for Transfer Belt defects varies considerably, depending on paper size and mode of operation. The defect may appear as frequently as every 3rd sheet, or may only occur every 14 sheets. The defect occurs in approximately the same position on multiple prints. YN If the defect occurs intermittently, examine the Developer Housings for evidence of toner clumping. If clumping is found, replace the Developer (PL 6.2). if this does not resolve the problem The defect is a full-width (LE - TE) process direction deletion. YN Remove the Fuser Assembly. Examine the Heat Roll for damage or contamination. Clean or replace as required (PL 7.1). If the Fuser is OK, check the Developer Housing (PL 6.2). Repair or replace as required. If the problem remains, replace the ROS (PL 3.1). If the problem is related to a single color, replace the Drum Cartridge (see Machine Con- sumables in Section 6). Enter dC612. Select Test Pattern 20% coverage pattern for all colors. The defect is present for all colors. YN ï Check the ROS window for damage or contamination. Clean or replace as required. ï Check Drum Cartridge for affected color. Check for damage or contamination to the BCR. ï Go to the IQ20 RAP to check the 1st BTR bias circuit for the affected color ï Replace the Developer (PL 6.2) for the affected color. Check the housing for damage or toner clumping. Remove the IBT Cleaner (PL 5.3). Inspect the cleaning blade and Mylar seal for damage. Clean or replace as required. If the IBT Cleaner is OK, check the Transfer Belt (PL 5.3) for damage or contamination. Ensure that there is no debris or loose wiring, etc. in contact with the belt. Clean or replace as required.

6/02 3-12DC1632/2240 IQ13, IQ14 Prelaunch Training/Review Image Quality IQ13 Unfused Copy RAPInitial ActionsReplace the paper in use with fresh, dry paper of the correct specification. Ensure that the media being used matches the settings on the UI screen or print driver. Using the next heavier setting may resolve the problem. If the Key Operator/Administrator has configured certain trays for a specific type of media, ensure that the specified media is actually loaded in those trays.ProcedureCheck the following: ï Check the Sensor Assembly (PL 7.2) for contamination or incorrect mounting. Clean, repair, or replace as required. ï Check the Fuser (PL 7.1) for damage, toner offsetting, paper wrap, or incorrect installa- tion. Clean or replace as required. IQ14 Repeating Bands, Streaks, Spots, and Smears RAPProcedureMeasure the distance between the repeating defects. Locate the distance on the table below.

6/02 3-13 DC1632/2240 IQ15, IQ16Image Quality Prelaunch Training/Review IQ15 Mottle RAPThis RAP troubleshoots the causes of output images showing image density that varies from inboard to outboard edges, or randomly throughout the print.Initial Actionsï Replace the paper in use with fresh, dry paper of the correct specification. Ensure that the loaded media matches the UI or print driver settings. ï Determine if the Drum Cartridge or any of the Toner Cartridges are approaching end-of- life. Replace if necessary. ï Perform Max Setup (ADJ 9.1). If this does not resolve the problem, continue with this RAP.ProcedureMake a print of the Test Page (??????). The defect involves a single color. YN Make a print of the Test Page. Open the Front Door when the lead edge of the print begins to protrude from the Fuser Exit nip. Open the Fuser and examine the partially- fused sheet. The defect is present in both the fused and unfused portion of the sheet. YN Clean or replace the Fuser (PL 7.1). Enter dC612. Make a print of Test Pattern???. As the print is being processed, open the Front Door. Examine the image on the Transfer Belt. The image on the belt has accept- able density. YN Replace the Transfer Belt (PL 5.3). Go to the IQ22 RAP to check 2nd BTR Backup Roll bias/contacts. Clean/replace the 2nd BTR Assembly (PL 7.1). If the problem continues, replace the Transfer Belt (PL 5.3). Switch Drum Cartridges. The problem moves with the cartridge. YN Check the following: ï Clean the HV contact for the developer in question. ï Replace the Toner Cartridge if not done previously. ï Replace the Developer (PL 6.2). Examine the housing for damage, wear, or contam- ination. If the problem persists, replace the ATC Sensor (PL 6.2). Replace the Drum Cartridge (see Machine Consumables in Section 6). IQ16 Spots RAPInitial ActionsEnsure that the paper in use is fresh, dry, and within specification for weight and quality. Check print driver and copier control panel settings to ensure the media is being un in the proper mode. Compare the spots against the samples in the Image Quality Defects supplement. If the defect matches the Debris Centered Deletions sample, go to the IQ9 RAP.ProcedureThe defect occurs in Copy mode only. YN The spots occur at a fixed interval on each print. YN The spots occur in the same location on every letter size print. YN NOTE: The repetition rate for Transfer Belt defects varies considerably, depending on paper size and mode of operation. The defect may appear as fre- quently as every 3rd sheet, or may only occur every 14 sheets. The defect occurs in approximately the same position on multiple prints. YN The problem is Fuser offset. YN CAUTION Do not use a vacuum cleaner or any solvents in the following step. Damage to the Belt Cleaner will result. Remove the Belt Cleaner (REP 9.16). Carefully clean the cleaning blade and the Mylar shield with a soft brush or a lint free cloth. Brush away any accumulation of toner on the foam seal and the outside surfaces. Wipe the surface of the Transfer Belt with a lint free cloth. If the problem continues, replace the Belt Cleaner (PL 7.1). Check the Fuser for dirt, damage, or toner buildup. Clean or replace as required (PL 7.1). Check the Transfer Belt (PL 5.3) for dirt or damage. Clean or replace as required. Check the Drum Cartridge for dirt or damage. Clean or replace as required ((see Machine Consumables in Section 6). Go to the IQ14 RAP. Ensure that the original is free from the defect. Clean the Platen Glass and Lens.

Enter dC140 [09-026]. Check the voltage at P/J 580 for the affected color(s). There should be approximately 370 VAC and -540 VDC (+/- 10%) present. The voltages are within range. YN There is +24 VDC from J 501 pin 13 to J 501 pin 10 on the HVPS T5 PWB. YN There is +24 VDC from J 553 pin 2 to J 553 pin 4 on the I/F PWB YN Go the +24 VDC Wirenets to troubleshoot this problem. Go to Flag 2. Check for an open circuit Check that the HVPS Control PWB is seated correctly. If the problem continues, replace the HVPS T5 PWB (PL 9.1). Go to Flag 1. Check for an open circuit or a short circuit to ground. Check P/J 580 and the HV terminals on the Developer Housing(s). for damage or loose connections. If the checks are good, return the RAP from which you came.
