CAUTION
This product is a class 1 laser product that complies with 21CFR 1040 of the CDRH standard and IEC825. This means that this machine does not produce hazardous laser radiation. The use of controls, adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
This laser radiation is not a danger to the skin, but when an exact focusing of the laser beam is achieved on the eye’s retina, there is the danger of spot damage to the retina.
The following cautions must be observed to avoid exposure of the laser beam to your eyes at the time of servicing.
1) When a problem in the laser optical unit has occurred, the whole optical unit must be exchanged as a unit, not as individual parts.
2) Do not look into the machine with the main switch turned on after removing the developer unit, toner cartridge, and drum cartridge.
3) Do not look into the laser beam exposure slit of the laser optical unit with the connector connected when removing and installing the optical system.
4) The middle frame contains the safety interlock switch.
Do not defeat the safety interlock by inserting wedges or other items into the switch slot.

B. Network tandem

With Network tandem function, users can output one job on two net­work connected engines. Productivity of large-volume copying/printing can be dramatically improved by high-speed output of up to 110cpm (55cpm model), 124cpm (62cpm model) and 140cpm (70cpm model)
Scan original from
Copy
document glass or DSPF

A. High reliability

(1) Improved Image Quality/Paper Transport
Full-Grip Path Design
Stable paper feeding realized by rollers that firmly grip paper
Small-Diameter Belt Transfer System
With reduced effect to paper types, drum paper release is stabilized and transfer efficiency is improved
Easier Paper Jam Fixation with Open Paper Path
Jammed paper on vertical paper path can be easily removed by open­ing the left side cover, which shortens time to fix paper jam
Send print data from PC

The finisher and the saddle stitch finisher include the offset function, which offsets each set of copies from the preceding set for easy separation. Each set of sorted copies can also be stapled. The saddle stitch finisher can automatically staple at the center line of a set of copies and fold the pages to create a pamphlet. A punch unit can be installed to add punch holes to copioes, and an inserter can be installed to insert blank pages at specified pages. Adds punch holes to printed pages.
The inserter enables blank sheets or printed sheets to be added to copy and print output as covers or inserts without printing. Printed output can also be fed one set at a time from the inserter for stapling or punching without performing stapling or staple sorting finishing.

B. Operational descriptions

(1) Paper feed operation
a. Preliminary operation before paper feed
1) Set paper in the tray, and insert the tray into the machine. The tray sensor turns on.
2) The lift-up motor operates to lift the tray.
3) The paper upper limit sensor turns on to stop the tray at the speci­fied position.
b. Paper feed operation
1) When copy/print operation is started, the motors (MM, FUM, VPM, and TRM) and the clutch (TRC) are turned on to turn on the sole­noid (T1PUS) at the timing of paper pickup. This rotates and falls the take-up roller to pick up paper.
2) At the same time, the paper feed roller rotates to feed paper to the transport section. At that time, the separation roller rotates to pre­vent against double feed of paper.

(2) Remaining paper detection
a. Remaining paper detection
Remaining paper detection is performed according to four stages, i.e. three stages with paper and one stage with no paper, and the result is displayed.
(Figure showing state transition of the remaining paper detection sensor during tray elevation and
changes in status according to the number of remaining sheets)
The no-paper detection sensor detects the state of no remaining paper.
During no-paper detection
b. Detection method
The number of remaining sheets is determined according to the num­ber of times the remaining paper sensor changes from the time the paper feed tray starts lifting up to the time when the upper detection sensor comes ON.

[Paper Transport Section] Outline
The paper transport section serves the function of transferring paper from each paper feed port to the registration roller section.
Paper from manual feed, paper feed tray units 1 and 2 (optional), and the right paper feed tray of the paper feed tray units 1 and 2 is trans­ported horizontally, whereas paper from the left paper feed tray of the paper feed tray units 1 and 2, paper feed tray 3 and paper feed tray 4 is transported vertically to the registration roller section.
After the leading edge of the paper is synchronized with the leading edge of the drum image in the registration roller section, the paper that is transfer printed with the image in the transfer section passes through the fusing section and is discharged either face-down or face-up.
