Cleaning Web/Web Pushing Roller; Thermistor - Toshiba e-STUDIO650 Service Handbook

*18 Cleaning web/web pushing roller

Take the following steps when replacing the cleaning web and web pushing roller.
1. Pull out the fuser unit, and take off the cleaning web unit (2 black screws).
2. Replace the cleaning web and web pushing roller.
Note: Be sure to replace both the cleaning web and web pushing roller. If only the web pushing roller is
continuously used, the cleaning web may be caught by the roller.
3. Take up the cleaning web a little (3~5 rotations with hand).
4. Install the cleaning web unit to the fuser unit. At this time, make sure that the web is not slacked
off.
5. Turn the fuser unit jam access knob 10~15 times to adapt the cleaning web to the fuser roller. At
this time make sure that there is no defect caused by an installing inadequacy.
6. Make sure that the cleaning web is not riveled or slacked off.
• Be sure that the cleaning web does not run over the space between the upper guide and fuser
roller when seen from the fuser unit entrance side.
• Open the upper separation finger unit and make sure that the cleaning web is not riveled or
slacked off.
7. Set up the PM support "6S" and clear the cleaning web counter.
After clearing it, the web motor automatically rotates for 65 seconds when turning the power ON.
Note: It is possible for the cleaning performance to be lowered unless the counter clear is not carried out.
8. Turn the power ON and make sure that "READY" is displayed.
9. Finally confirm the fuser unit is in a proper condition (same as the above 6).
Note: Do not rotate the web motor for more than 2 min. at the output check (03-124) since the cleaning web
may be slacked off when rolled up.

*19 Thermistor

Clean the thermistor with alcohol if the toner or dirt is sticking to it when the fuser roller is replaced.
Do not deform or damage the thermistor during the cleaning. Replace the thermistor with a new one if
it is damaged or deformed regardless of degree.
