* a1. Original glass / ADF original glass Clean both sides of the original glass and ADF orig inal glass.
Note: Note: 
Make sure that there is no fingerprints or oil stain ing on part of the original glass on where the 
original scale is mounted since the shading correcti on plate is located below the scale to be 
scanned.

* h1. Drum cleaning blade Since the edge of the blade is vulnerable and can be  easily damaged by factors such as 
the adherence of paper dust. Replace the cleaning b lade with new ones if poor images are 
printed due to the damaged blade regardless of the  number of output pages if which have 
been made.
* h2. Separation fingers for drum The paper jam may be caused if the tip of the separ ation finger is damaged or deformed. If 
there is any problem with it, replace the finger wit h a new one regardless of the number of 
output pages which have been made. 
If any mark which was made by the finger appears on  the printed image, clean the tip of 
the finger.
Notes:  1. Wipe the tip of the finger lightly with a dry clo th trying not to deform it.
Do not leave the lint on the tip.
2. Apply patting powder to the tip of the fingers an d drum surface after replacing or cleaning 
them to reduce the load on the drum surface by the  finger.
* h3. Recovery blade Replace the recovery blade regardless the number of  output pages if the edge of the blade 
get damaged.
* i1. Developer material After replacing the developer material, be sure to  perform the auto-toner adjustment.
(   P. 3-1 3.1 Adjustment of Auto-Toner Sensor)
* i2. Oil seal (Developer unit) Mixer unit (Shafts of mixers-1, -2 & -3) 6 pcs.
During replacement, coat the oil seal with grease ( Alvanian No.2).
(1) Push in a new oil seal parallel to the mount- ing hole section of the developer frame or  
outside of the holder. 
* Pay attention to the direction in which the oil seal is attached. (See figure on right.)
(2) Apply an even coat of grease to the inside of  the oil seal. 
 Amount: About two small drops

4.8 Precautions for Storing and Handling Supplies 
4.8.1 Precautions for storing TOSHIBA supplies
1) Toner/Developer
Toner and developer should be stored in a place whe re the ambient temperature is between 10°C to 
35°C (no condensation), and should also be protecte d against direct sunlight during transportation.
2) Photoconductive drum Like the toner and developer, photoconductive drum  should be stored in a dark place where the 
ambient temperature is between 10°C to 35°C (no con densation). Be sure to avoid places where 
drums may be subjected to high humidity, chemicals  and/or their fumes.
3) Drum cleaning blade This item should be stored in a flat place where th e ambient temperature is between 10°C to 35°C, 
and should also be protected against high humidity,  chemicals and/or their fumes.
4) Fuser roller / Pressure roller / Cleaning roller Avoid places where the rollers may be subjected to h igh humidity, chemicals and/or their fumes.
5) Paper Avoid storing paper in places where it may be subje cted to high humidity.
After a package is opened, be sure to place and sto re it in a storage bag.

4.8.2 Checking and cleaning of photoconductive drum
1) Use of gloves If fingerprints or oil adhere to the drum surface,  the property of the photoconductive drum may 
degrade, affecting the quality of the print image.  So, do not touch the drum surface with bare hands.
2) Handling precautions As the photoconductive drum surface is very sensitiv e, be sure to handle the drum carefully when 
installing and removing it so as not damage its sur face.
Be sure to apply “patting powder” (lubricant) to th e entire surface of the drum (including both ends o f 
the drum where OPC is not coated) when replacing th e drum. When the drum has been replaced 
with a new one, the drum counter (the Setting Mode  08-1150-0, 3, 6 and 7) must be cleared to 0 
(zero). 
This clearing can be performed in the PM Support Mo de.
Notes: 
 Application of the patting powder is for reducing  the friction between the drum and cleaning 
blade. If the application of patting powder is negl ected, the drum and cleaning blade may be 
damaged.
 When paper fibers or dint adhere to the cleaning b lade edge, they may reduce the cleaning 
efficiency and, in addition, may damage the blade a nd the drum. Be sure to remove any fibers 
found adhering to the blade.
3) Installation of the equipment and storage of drum Avoid installing the equipment where it may be subj ected to high temperature, high humidity, chemi-
cals and/or their fumes. 
Do not place the light drum in a location where it  is exposed to direct sunlight or high intensity light 
such as near a window. Otherwise the drum will fati gue, and will not produce sufficient image den-
sity immediately after being installed in the equip ment.
4) Cleaning the drum At preventive maintenance calls, wipe the entire sur face of the drum clean using the designated 
cleaning cotton. Use sufficiently thick cleaning co tton (dry soft pad) so as not to scratch the drum 
surface inadvertently with your fingertips or nails.  Also, remove your rings and wristwatch before 
starting cleaning work to prevent accidental damage  to the drum.
Do not use alcohol, selenium refresher and other or ganic solvents or silicon oil as they will have an 
adverse effect on the drum.
5) Scratches on photoconductive drum surface If the surface is scratched in such a way that the a luminum substrate is exposed, no print image will 
be produced on this area. In addition, the cleaning  blade will be damaged so replacement with a 
new drum will be necessary.
6) Collecting used photoconductive drums Regarding the recovery and disposal of used photocon ductive drums, we recommend following the 
relevant local regulations or rules.

4.8.3 Checking and cleaning of drum cleaning blade
1) Handling precautions
Pay attention to the following points as the cleanin g blade life is determined by the condition of its 
edge: 
- Do not allow hard objects to hit or rub against bl ade edge.
- Do not rub the edge with a cloth or soft pad. 
- Do not leave oil (or fingerprints, etc.) on the edg e.
- Do not apply solvents such as paint thinner to the  blade.
- Do not allow paper fibers or dirt to contact the bl ade edge.
- Do not place the blade near a heat source.
2) Cleaning procedure Clean the blade edge with a cloth moistened with wa ter and squeezed lightly.
4.8.4 Checking and cleaning of fuser roller and pres sure roller
1) Handling precautions
- Fuser rollerDo not leave any oil (fingerprints, etc.) on the fu ser roller.
Be careful not to allow any hard object to hit or r ub against the fuser roller, or it may be damaged, 
possibly resulting in poor cleaning.
- Pressure roller Do not leave any oil (fingerprints, etc.) on the pr essure roller.
2) Checking - Check for stain and damage on the fuser and pressu re rollers, and clean if necessary.
- Check the separation guide and fingers and check f or chipped tips.
- Check the cleaning effect of the cleaning roller. 
- Check the thermistors for proper contact with the  pressure roller.
- Check the fused and fixed condition of the toner. 
- Check the gap between the entrance guide and press ure roller.
- Check the fuser roller for proper rotation.
3) Cleaning procedure When fuser roller and pressure roller become dirty,  they will cause jamming. If this happens, wipe 
the surface clean with a piece of soft cloth. For e asier cleaning, clean the roller white they are still 
warm.
Note: Note:  Be careful not to rub the fuser roller and pressure  roller surface with your nails or hard objects 
because it can be easily damaged. Do not use silico ne oil on the fuser roller and pressure roller.
4.8.5 Checking and replacing the cleaning roller
1) Handling precautions
Never allow solvents such as paint thinner to touch  to the cleaning rollers.
2) Poor cleaning and corrective treatment Judgment should be made depending on how much toner  has been deposited on the pressure roller 
surface. When its surface is stained with toner, ch eck the cleaning roller. If toner is heavily adhered 
on the cleaning roller, the cleaning roller should  be replaced with new ones.
Replace it when a specified number of output pages  have been made.
