Symptoms
The press console displays error 1020, indicating a sheet feeder jam. The feeder section has detected a sheet that was not properly separated or transported, causing a stop to prevent damage to the feeder mechanism and printing cylinders.
Possible Causes
- Suction head air pressure incorrect for the paper weight being run
- Separator blower air setting incorrect causing double-sheet feeding
- Feeder table pile height too high or pile not properly jogged
- Suction cup or transport gripper worn or damaged
Troubleshooting Steps
- Step 1: Check and adjust the suction head air pressure for the paper weight
Increase suction for heavier paper, decrease for lighter paper - Step 2: Adjust the separator blower air to prevent double sheets
Verify separator is properly positioned and air flow is correct - Step 3: Check the feeder table pile height and jog quality
Rejog the pile if edges are uneven, adjust pile height sensor - Step 4: Inspect suction cups and transport grippers for wear
Replace worn suction cups and adjust gripper bar timing
How to Reset
To reset 1020: 1) Clear the jammed sheet from the feeder path. 2) On the console, press the Reset button. 3) The feeder performs a self-check. 4) Press the Start button to resume printing. 5) Monitor the first few sheets for proper feeding.
Common Replacement Parts
- HD-106-001: Feeder suction cup set, 4 pieces (Replace at 1000 hours or when showing cracks)
- HD-106-005: Separator blower nozzle assembly (Clean weekly, verify air flow direction)
- HD-106-010: Feeder pile height sensor, ultrasonic (Verify calibration monthly)
Frequently Asked Questions
- Q: How do I prevent sheet feeder jams?
Use correct suction and blower settings for each paper type, maintain proper pile height and jog quality, replace suction cups regularly, and verify feeder sensor calibration. Always run test sheets at reduced speed when changing paper stock.
- Q: What suction pressure should I use for different paper weights?
For text weight paper (80-120 gsm), use 40-50% suction. For cover weight (200-300 gsm), use 60-75%. For board (300+ gsm), use 75-90%. Adjust within these ranges based on the specific paper surface characteristics and humidity conditions.
