/ SETTING
13.4.19 THICK MODE
A. Use
• In order to prevent toner from clogging within the developer unit as a result of it being
driven at half-speed, select the timing for driving the developer unit at full speed for a
fixed length of time when thick paper is being fed.
QUALITY MODE: While printing on thick paper, printing is periodically paused, and the
developer unit is driven at full speed for a fixed length of time. Since
printing is paused, the quality is not affected; however, a standby time
of approximately 70 seconds occurs every 400 seconds or so of half-
speed operation.
SPEED MODE: While printing on thick paper, only the drive of the developer unit peri-
odically switches to full speed for a fixed length of time.
Since printing continues during full-speed drive, the print quality is
slightly affected, however the standby time is short.
B. Procedure
• The default setting is QUALITY MODE.
