Table 7-3. Numerical printer messages (continued) Message Description Action Four color slippage bands occur across the ITB belt because the right side cleaning blade shipping tab is out of position. This can cause interference with the yellow cartridge, where the cleaning blade shipping tab contacts the OPC white plastic hub and the OPC ground contact adjacent to the OPC hub. This interference between the cleaning blade and the yellow cartridge prevents the proper engagement between the ITB drive roller coupler and the engine ITB resulting in non-engagement of the ITB drive roller coupler to the engine which can produce separate color toner slippage bands across the ITB belt surface beneath each toner cartridge. You may also hear a thumping noise and experience a vibration in the upper right portion of the front cover. Due to the interference, a paper jam 13.xx.xx error (13.20.00 on an HP 3700 with a corresponding 13.05.00 paper jam in the event log, or a 13.50.00 message for an HP 3500/3550 printer). Perform the following steps to fix the problem: 1. Right side cleaning tab is out of position. (This tab is located on the right side of the ITB, about in the middle of the ITB assembly .) Push it back into position. If it will not move back into position, replace the ITB assembly. 2. Check the yellow cartridge for damage (compare it to the magenta cartridge) and replace it if necessary. 3. Verify that the cleaning blade left-hand tab lock lever is in the forward position. 4. Verify that the ITB assembly shipping locks have been removed. Shipping locks are located at the bottom (toward the door hinge end) of the ITB assembly on the left and right side.
