Envelope Selector - Ricoh J012 Service Manual

ENVELOPE SELECTOR

Move the envelope selector [1] to adjust size of the gap between the print heads and the
surface of the paper.
Pushing the lever to the back moves the print heads slightly away from the surface of thick
paper and envelopes. This prevents chaffing the printed surface and smearing ink.
A cam operates when the envelope selector pushed back for printing on thick paper or
envelopes. This moves a guide rod to create a gap about 0.8 mm wider than the gap for
normal printing. Normally, this lever should be set forward for printing on normal paper.
When the envelope selector is pushed back, this raises a feeler into the gap of the carriage
position sensor. When the envelope selector is pulled forward, the feeler leaves the gap and
switches the sensor off. This mechanism is used to detect the up and down position of the
carriage and print heads.
