Large curl of paper
Location
Fixing Assembly
Cause
Excess heat from fixing changes moisture content between the front and back of paper, which causes large curl.
Condition
Paper left untouched in a high humidity environment
Field Remedy
• Service mode (Lv.2)> COPIER> OPTION> IMG-FIX> TMP-TBLC> 0 to 3
0: Auto
1: OFF
2: N1 mode with plain paper 1/2 (Target temperature becomes low.)
3: N3 mode with plain paper 1/2 (Target temperature becomes moreover low.)
Paper jam in solid image when the leading edge margin is small (1 to 4mm)
Location
Fixing Assembly
Cause
When handling a solid image with small leading edge margin (1 to 4mm), it causes poor paper separation from the Fixing Film and paper jam can occur by separation failure.
Condition
Paper left untouched in a high humidity environment, solid image with small leading edge margin
Field Remedy
- Service mode (Lv.2)> COPIER> OPTION> FEED-SW> SP-SW> 0 to 2
0: OFF
1/2: Separation priority mode - Or Service mode (Lv.2)> COPIER> OPTION> IMG-FIX> TMP-TBLC> 0 to 3
0: Auto
1: OFF
2: N1 mode with plain paper 1/2 (Target temperature becomes low.)
3: N3 mode with plain paper 1/2 (Target temperature becomes moreover low.) - Selecting "SP-SW > 1/2" or "TMP-TBLC > 3" makes a wider leading edge margin and avoids paper jam by separation failure.
- Selecting "TMP-TBLC > 2/3" also improves paper curl; however, it reduces productivity
