CAUTION:

!

When you are choosing print media, be sure to follow the information given below to prevent
any paper jams, print quality problems or machine damage;

• It is recommended to use long-grained paper for the best print quality. If short-grained
paper is being used, it might be the cause of paper jams.

• Use neutral paper. Do not use acid paper to avoid any damage to the drum unit.

• Avoid using coated paper such as vinyl coated paper.

• Avoid using preprinted or highly textured paper.

• It is recommended to use labels or transparencies which are designed for use in laser

printers.

• Avoid feeding labels with the carrier sheet exposed, or the machine will be damaged.

• Before loading paper with holes such as organizer sheets, be sure to fan the stack well.

• Do not use organizer sheets that are stuck together. The glue that is used might caused

damaged to the machine.

• When printing on the back of pre-printed paper, if the paper is curled, be sure to straighten
the paper as much as possible.

• Different types of paper should not be loaded at the same time in the paper tray to avoid
any paper jams or misfeeds.

CHAPTER 1 GENERAL

2.13 Print Speeds with Various Settings

Print speed of the machine is up to 18cpm when loading A4 size paper from the paper tray in
the plain paper mode.
Actual print speed varies depending on the paper type or paper size as shown in the tables
below;

< Letter or A4 size >

< Smaller size than Letter or A4 >

Mode setting Print speed
OHP
Plain paper
Rather thick plain paper/Thin envelope
Thick paper (Post card)/Envelope
Extra thick paper/Bond paper/ Rather thick envelope

*The print speed may vary according to conditions, such as paper size and paper tray.
NOTE:

• When a smaller size paper than A4 size is printed, the temperature on both edges of the
fixing unit is much higher than the temperature on the center of the unit where the paper is
fed depending on the setting or model. Therefore, the print speed is slowed in order to
decrease the temperature on the edges after the specified time, it is maximum print speed
when you first start printing.

• Max. speed is 20 cpm or more. It varies depending on the paper size.

This mechanism consists of the ADF document support, automatic document feeder (ADF),
document ejection roller ASSY, and document sensors. (For details about the sensors, refer to
Section 2.4.)

If you set documents on the ADF document support with their faces down and start scanning
operation, then the scanner motor rotates so that the ADF (which consists of the document
take-in roller ASSY, nip-related parts, separation roller ASSY, and ADF parts) feeds those
documents into the equipment, starting from the bottom sheet (first page) to the top (last
page), page by page. Each document advances with the document feed roller ASSY to the
scanner, and then it is fed out of the equipment with the document ejection roller ASSY.

First feed pinch roller

The paper is gripped between the paper pick-up roller and the separation pad and separated
into individual sheets.

The pick-up roller is directly connected to the clutch mechanism, whose rotation is stopped by
the stopper arm. When the pick-up solenoid is activated, the clutch mechanism is engaged by
the solenoid action and the paper pick-up roller is driven. The paper drawn out of the tray by
the pick-up roller pushes against the regist front actuator and the paper top position/absence of
paper is detected by sensing the motion of the actuator.

2.3.2 Paper registration

After the paper top position is detected by the regist front actuator, the paper, separated into
individual sheets by the paper pick-up roller, is fed further for a specified time, and the paper
top position reaches the paper feed roller so that the paper skew is adjusted. Then, the
solenoid is turned off, the paper feed roller starts turning, and the paper is fed to the transfer
block in the drum unit.

2.3.3 Paper eject

After the printing image on the photosensitive drum is transferred onto the paper, the paper is
fed to the fixing unit to fix unfixed toner onto the paper.

Afterwards, the paper is ejected from the fixing unit by the first eject roller in the fixing unit.
The paper eject actuator detects whether the paper is ejected correctly or not.

After the paper exits from the first eject roller, the paper is turned by the rear cover and ejected
face down into the top output tray through the second eject roller. If the rear cover is open, the
paper is ejected face up straight to the printer rear (straight paper path).

2.7 Print Process

2.7.1 Charging

The drum is charged to approximately 870V by an ion charge which is generated by the
primary charger. The charge is generated by ionization of the corona wire, which has a DC
bias from the high-voltage power supply applied to it. The flow of the ion charge is controlled
by the grid to ensure it is distributed evenly on the drum surface. The aluminum drum sleeve
in the photosensitive drum is grounded.

The primary charge uses a corona wire, but since the drum is positively charged, only less than
1/10 of the usual quantity of ozone is generated compared with the negatively charged drum.
The level of ozone expelled from the printer is therefore not harmful to the human body.
Applicable safety standards have been complied with.

2.7.3 Developing

Developing causes the toner to be attracted to the electrostatic image on the drum so as to
transform it into a visible image.

The developer consists of a non-magnetic toner. The development roller is made of
conductive rubber and the supply roller (which is also made of conductive sponge) rotate
against each other. The toner is charged and carried from the supply roller to the development
roller. The toner adheres to the development roller and is conveyed to the photosensitive drum
at an even thickness controlled by the blade. The toner is nipped between the development
roller and the drum and developed onto the latent image on the drum. The electrostatic field
between the drum and the development roller, which is DC-biased from the high-voltage power
supply, creates the electrostatic potential to attract toner particles from the development roller
to the latent image area on the drum surface.

Corona wire

Development rolle

Photosensitive drum

2.7.4 Transfer

(1) Transfer process

After the drum has been charged and exposed, and has received a developed image, the
toner formed is transferred onto the paper by applying a negative charge to the back of
the paper. The negative charge applied to the paper causes the positively charged toner
to leave the drum, and adhere to the paper. As a result, the image is visible on the paper.

Transfer rolle

Blade

Supply roller

Fig. 3-33

(2) Cleaning process of transfer roller

If the toner is not transferred onto the paper perfectly it is possible that there may be
residual toner on the drum which will adhere to the transfer roller. The transfer voltage
changes to a positive voltage during non-printing rotation of the drum. Therefore the
transfer roller is cleaned by returning the positively charged toner adhering to the transfer
roller onto the photo-conductive drum.

3-22

2.7.5 Fixing stage

The image transferred to the paper by static electricity is fixed by heat and pressure when
passing through the heat roller and the pressure roller in the fixing unit. The thermistor keeps
the surface temperature of the heat roller constant by detecting the surface temperature of the
heat roller and turning on or off the halogen heater lamp.
