| Problem | Solution |
|---|---|
| Pale lines/pressure marks |
Plates: - check plates from different batches and compare pressure marks. Processor: -Ensure that the developer is standard and fresh; Lotem: -Load/unload rollers springs press to hard on the plate; |
| Clean or replace wheels, make sure wheels are rolling freely with no excess friction (The whole support P/N is 507A20414) | |
| Cassette is too high relative to machine, therefore cassette rollers press hard on the plate | Readjust machine height to the maximum possible |
| Cassette rollers are stuck or not rolling freely |
Clean and remove residues of silicon rubber that may be around roller |
| Cassette rollers not smooth | Replace damaged rollers (P/N 290E9L765) |
| Cassette rollers still scratching the plate |
Replace hard rollers with soft ones- P/N # 290A2U472 (x 35 rollers) |
| Plate is being dragged/pressed to hard against disposal rollers during X motion |
Raise Y during X motion over the disposal rollers; Relevant parameters: Loading System/Loading System Setup/ “Y_Extra_To_Detector “ Loading System/Load Plate/From Cassette to Punch Stage/ “Y Up After_Cantring” |
| Disposal rollers still scratching the plate | Replace hard rollers with soft ones- P/N # 290A2S981(x75 rollers) |
| Protruding tie-wraps along punch beam scratch the plate | Remove protruding tie-wrap and replace with new one, making sure the connection and tip are facing sideways and not upwards |
| Dots/pinholes appear on the plate, lined in constant intervals along drum circumference axis | Usually caused by the upper or lower load rollers. Remove assembly and check rollers and their springs (P/N 290A4L268),Roller (P/N290F2M754+290F2M755)(whole assembly: Upper roller Assy P/N 510P51270, Lower roller Assy P/N 510P51271) |
| Rollers beneath gripper actuators beam not rolling free | Check rollers for free rotation, remove to clean if necessary |
|
Plate leader rollers (under the drum) Are stuck/not clean/not smooth |
Clean rollers or replace whole assembly if necessary (P/N 510P1P590, for VL P/N 510K1P260) |
| Plate leader hinges are protruding beyond rollers radius and touch the plate (Some were badly manufactured) | Replace the whole assembly with new P/N 510P1P590 (for VL P/N 510K1P260) |
