Riso HC5500 - Page 9

Cause of the problem (2)
The gap between Print Head and the transfer belt is too far.
- Ink mist, a minute particle of ink, may be sometimes generated from Print Head during printing.
- Such ink mist drifts in the air and comes toward the transfer belt.
- Most of them reach to the paper on the transfer belt so it is a problem.
- But if the gap between Print Head and the transfer belt is too far, misting ink may reach to the transfer belt and it can be
misting a cause of the problem.
- As a result, the surface of the transfer belt becomes dirty with ink and the edge of paper gets stained with ink.
- If the margin around the printing paper is reduced by menu 4.10 [Print Area], this problem occurs easily.
The gap is small (Normal)
The gap is big
Solutions
- Adjust the gap by SE mode 5.9.1.32 for HC5000. (It is possible to widen with 0.1mm step)
- The gap is alternated automatically by the paper type. If you print normal paper with envelope setting, the gap becomes
too big.(HC5500)
- Adjust print area(margin) by menu 4.10.(HC5000, HC5500)
<Tips>
- Default margin of normal paper by menu 4.10 is 5mm.(HC5000, HC5500)
- Maximum margin of normal paper by menu 4.10 is 1mm.(HC5000, HC5500)
- Default margin of envelope by menu 4.10 is 10mm.(HC5500) HC5000 cannot print with envelope.
