BASIC OPERATION 20 March 1998
2. DETAILED DESCRIPTIONS
2.1 BASIC OPERATION
[A]
[B]
G696D504.WMF
The four-bin mailbox is electrically connected to the base printer by an eight-pin
connector. One of these pins acts as a connection det ection mechanism.
Feed
When the mailbox is selected as the output tray and the lower exit sens or of the
base printer is actuated by the leading edge of the paper, the mailbox main motor
turns on, turning the transport rollers.
Soon after the main motor starts, t he turn gate solenoid energizes to direct the
paper to the four-bin mailbox. (If the standard output tray is selected, the turn gate
solenoid does not energize.) Then the selected tray solenoid [A] energizes, to
direct the paper to that tray. (If the 5th tray is selected, no solenoid turns on.)
When the last printout passes the transport s ensor and feeds out, the t ray sol enoi d
and the main motor turn off.
Normally, the paper transport speed is 180 mm/s. This speed is reduced to 114
mm/s when a large paper size is used (such as DLT or A3), to synchronize feed
speed with the fusing unit while part of the paper is still left in the fusing unit.
G696-4
20 March 1998 BASIC OPERATION
Jam Detection
Two transport sensors, lower and upper, detect misfeeds within the unit. When the
2nd or 3rd tray is selected, the lower transport sensor (located just before the feedout section of the 2nd tray) monitors misfeeds. When the 4th or 5th tray is selected,
both sensors monitor misfeeds. Only the lower transport sensor is used to control
the on/off timing of the tray solenoids for prin ts that are fed out to the 3rd and 4th
trays. (For details, refer to the timing charts.)
Paper Sensors
Each tray has a paper sensor [B] to detect paper i n the t r ay. E ach tray is monitored
to ensure that the tray does not contain more than 125 prints. If a print job of more
than 125 sheets is executed, the base printer will do up to 125 prints, then an error
message will appear in the printer display panel and the printing job is stopped.
Once the output stack is removed, the printing job automatically continues.
