Ricoh A224 Service Manual

A224 COPIER

SERVICE MANUAL

The A224 copier is based on the A193 copier.

Only the differences from the base copier are described
in the following pages. Therefore, this document should
be treated as an insert version of the base copier’s
service manual, although it has a separate binder. It
should always be used together with the base copier’s
service manual.

IMPORTANT SAFETY NOTICES

+

PREVENTION OF PHYSICAL INJURY

1. Before disassembling or assembling parts of the copier and peripherals,
make sure that the copier power cord is unplugged.

2. The wall outlet should be near the copier and easily accessible.

3. Note that some components of the copier and the paper tray unit are
supplied with electrical voltage even if the main switch is turned off.

4. If any adjustment or operation check has to be made with exterior
covers off or open while the main switch is turned on, keep hands away
from electrified or mechanically driven components.

5. If the Start key is pressed before the copier completes the warm-up
period (the Start key starts blinking red and green alternatively), keep
hands away from the mechanical and the electrical components as the
copier starts making copies as soon as the warm-up period is
completed.

6. The inside and the metal parts of the fusing unit become extremely hot
while the copier is operating. Be careful to avoid touching those
components with your bare hands.

HEALTH SAFETY CONDITIONS

1. Never operate the copier without the ozone filters installed.

2. Always replace the ozone filters with the specified ones at the specified
intervals.

3. Toner and developer are non-toxic, but if you get either of them in your
eyes by accident, it may cause temporary eye discomfort. Try to remove
with eye drops or flush with water as first aid. If unsuccessful, get
medical attention.

OBSERVANCE OF ELECTRICAL SAFETY STANDARDS

1. The copier and its peripherals must be installed and maintained by a
customer service representative who has completed the training course
on those models.

2. The RAM board on the system control board has a lithium battery which
can explode if replaced incorrectly. Replace the battery only with an
identical one. The manufacturer recommends replacing the entire RAM
board. Do not recharge or burn this battery. Used batteries must be
handled in accordance with local regulations.

SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL

1. Do not incinerate toner bottles or used toner. Toner dust may ignite
suddenly when exposed to an open flame.

2. Dispose of used toner, developer, and organic photoconductors in
accordance with local regulations. (These are non-toxic supplies.)

3. Dispose of replaced parts in accordance with local regulations.

4. When keeping used lithium batteries in order to dispose of them later,
do not put more than 100 batteries per sealed box. Storing larger
numbers or not sealing them apart may lead to chemical reactions and
heat build-up.

LASER SAFETY

The Center for Devices and Radiological Health (CDRH) prohibits the repair
of laser-based optical units in the field. The optical housing unit can only be
repaired in a factory or at a location with the requisite equipment. The laser
subsystem is replaceable in the field by a qualified Customer Engineer. The
laser chassis is not repairable in the field. Customer engineers are therefore
directed to return all chassis and laser subsystems to the factory or service
depot when replacement of the optical subsystem is required.

WARNING

+

Use of controls, or adjustment, or performance of procedures other than
those specified in this manual may result in hazardous radiation exposure.

WARNING FOR LASER UNIT

+

WARNING: Turn off the main switch before attempting any of the

procedures in the Laser Unit section. Laser beams can
seriously damage your eyes.

6. MAIN SCAN MAGNIFICATION/REDUCTION

The specification of the reproduction ratios in the memory mode (binary
picture processing mode) has been changed to 5 enlargement and 6
reduction. This is because the higher copy speed of this model causes poor
copy quality at a reproduction ration of 25%.

Reproduction ratios of 48% ~ 400% are achieved for main and sub scan
magnifications in the same way as for the A193 copier, and for reproduction
ratios of 25% ~ 47%, it is done by changing the scanner speed and deleting
every other line.

The strength of the beam is 0.6 mW on the drum surface (10 mW output from
the LDDR board) at a wavelength of 780 nm.

The polygon motor speeds have been changed as follows:

The polygon mirror motor and motor driver are separated to prevent the laser
unit from being heated by the motor driver. Also, the laser unit has a polygon
motor cover and shield glass to reduce the noise from the polygon motor.

The fusing edge thermistor is for over heat prevention at the end of the hot

A224D207.wmf

The pressure of the pressure roller can be changed in the same way as for
the A193 machine. It is done by adjusting the position of the pressure springs
[A]. In this machine, the fusing pressure can also be adjusted with the lever
handle [B] (this is a finer adjustment than the pressure springs). The user can
do this when printing on a thicker medium, such as an envelope.

The lever shaft [C] contacts the pressure lever [D]. When the lever handle
rotates down, the shaft lowers the pressure lever. At this time, the pressure of
the pressure roller is decreased. The upper position of the lever is normal.

10.3 FUSING UNIT FAN

[A]

A224

Copier

A224D505.wmf

The fusing unit fan [A] has been added below the fusing unit. The fusing unit
fan is necessary because the wattage of the fusing lamp is higher than in the
A193 machine, as a result of the higher copy speed.

The fusing unit fan turns on if the charge roller thermistor detects a
temperature in the machine of over 43°C when the main motor starts to rotate
or at any time that the main motor is rotating.

The fusing unit fan stops either when the main motor stops or when the
temperature in the machine falls below 40°C.

IMAGE FUSING 25 April 1997

10.4 FUSING TEMPERATURE CONTROL AND OVERHEAT
PROTECTION

[B]

[A]

A224D504.wmf

The fusing control type can be either phase control or on-off control,
depending on an SP mode setting.

The fusing edge thermistor [A] has been added. It measures the temperature
at the end of the hot roller. This is because this machine has a higher copy
speed and more power is supplied to the fusing lamp. So, when making a
multi-copy run with A4 size paper, the temperature at the ends of the hot
roller is higher than at the middle.

Usually, the fusing temperature is controlled using the fusing thermistor [B]
(at the middle). However, if the temperature at the end of the hot roller
becomes greater than 230° C, the fusing lamp turns off until the temperature
at the middle of the hot roller has fallen by 5°C.

25 April 1997 ENERGY SAVER MODES

11. ENERGY SAVER MODES

Basically, the function and performance of the energy saver mode in all
machine configurations, except the copier configuration for the 230V
machine, are the same as for the A193 machine. The following are the items
which have been changed.

1. Fusing temperature in the energy saver level 2

80°C (230V machine)

2. The recovery time from energy saver level 2

30 s (230V machine)

3. When the auto shut-off timer runs out in the copier configuration (230V

machine only)
When the auto shut-off timer runs out, the machine enters auto shut off
mode and the

ac switch

turns off automatically. This function can be
disabled with SP 5-948. If this function is disabled, the main switch turns
off when the timer runs out.

NOTE:

This function is necessary to meet new BAM regulations in
Germany (enforced from January, 1999). The new BAM
regulation requires low power consumption in the auto-shut off
mode (less than 2 W).
