Image Problem. WATER SPOTS FROM CONDENSATION
After a log job (about 20 sheets of A4) printing on single-sided sheets, water drop patterns may appear in the following duple print job. This is likely to occur in a cool environment, especially early in the morning before the machine is sufficiently warm.
Cause
Water in the paper evaporates and accumulates in the duplex paper path during simplex printing. The paper collects the water when it passes through the duplex path which leads to poor image transfer.
Action
- Wait at least 5 min. after a long simplex print job before starting a duplex print job.
- Set “Curl Prevention” to ON.
MF model: User Tools > Machine Features > Maintenance > Curl Prevention: Active
Printer model: Menu > Maintenance > Quality Maintenance > Curl Prevention: Active
Note:
If set to [Active]:
- The print speed drops (30ppm). Accordingly, the first print output time is delayed.
- The fixing ability might worsen depending on the paper used.
- If "Thick Paper 2" or heavier is selected, the print speed drops around 23ppm.
- If "Thick Paper 1" or heavier is selected, idle rotation 10 seconds is added before printing.
