Development Entrance Seal Replacement

Part information Electrical Transmit/receive

Prepared by:

This is to inform about a problem that could occur in theory. This problem, however, will not occur at an early stage but may develop as the machine is

used over a long period of time. This problem may only occur when the photoconductor gap (PG) is at the narrowest setting (0.65 mm) and the doctor gap is at the widest setting (0.70 mm). This PG/DG setting does not exist in production machines as far as checked in the factory but is still within the adjusting range.

- Problem -

The lower seal (straight; the upper seal is a loop) of the development unit entrance seal ass'y (P/N A2293092) may get pinched between the developer and the drum if a large amount of developer accumulates near the photoconductor gap (PG). The seal may be pulled out of position by the friction caused by the rotation of the drum. In the worst case, the seal would peel off.

Upper seal

Lower seal

Drum

Developer accumulation

- Cause -

The width of the lower seal is 18 mm, which may be too much. This problem does not occur with the previous entrance seal ass'y (P/N A0963103) that has a width of 17mm.

- Countermeasure -

The width of the lower seal will be returned to the original 17 mm from 18 mm. Though the 17 mm lower seal may wrap up, the function of this part is not adversely affected. The part number of the new development unit entra nce s eal ass'y will be A2293091.

This is to inform you about troubleshooting when black spots appear on the first copy after warming up.

Problem

Black spots may appear on the front or rear side of the first copy after warming up. The diameter of the spots is 3 mm at most. The number of spots may be around 20 in the worst case.

Cause

When the machine turns off and the temperature of the fusing unit becomes low, toner adheres less strongly to the hot roller cleaning roller [A] and pressure roller cleaning roller [B]. In this condition, the toner on the hot roller cleaning roller [A], pressure roller cleaning roller [B] or pressure roller cleaning brush [C] may be transferred back to the hot roller or pressure roller and may finally adhere to the first copy after warming up.

This problem depends on how much calcium carbonate comes out from the copy paper and mixes with toner. When more calcium carbonate is mixed with toner, the problem becomes worse if the brush [C] is not installed.

According to tests, many brands of paper in Europe and Asia include a lot of calcium carbonate and many of the American ones do not. That is why the pressure roller cleaning brush [C] is installed only in the European and Asian/Oceanian models to remove toner from the pressure roller cleaning roller [B]. (The brush is not installed in the American model.)

Model: SP5 Date: 30-Nov-98 No.: 5

Action

1. Please change the setting of SP1-103 from 0 (5.5 min) to 2 (15 min). A longer fusing idling time can help to make the temperature of the pressure roller just after warming up higher.

2. Please judge the necessity of the pressure roller cleaning brush by looking how the mixture of toner and calcium carbonate adheres to the cleaning roller surface.

- Not necessary -

The brush is not necessary when the surface of the hot roller cleaning roller and pressure roller cleaning roller looks shiny like the pictures below.

- Necessary -

The brush (A229 4153) is necessary when the surface of the hot roller cleaning roller and pressure roller cleaning roller does not look smooth, with many small balls with the mixture of toner and calcium carbonate like in the pictures below.

This is, however, just a recommended guideline and does not match all cases in the field. Even in one machine, the condition of the cleaning roller surface may change in any of the following operations.

With analog copiers, it has not been necessary to think about confidentiality of originals used for copying. Our copiers have recently been shifting from analog to digital in many segments. Since most digital copiers have a hard disk that can store scanned originals for job completion (such as collating), we must prevent the scanned originals from being recalled from the hard disk by someone else.

The following explains how the software handles the scanned images on the hard disk. Please explain to the customers when required.

In the copy mode, when an original is scanned, the scanned original is stored as image on the hard disk. The stored image on the hard disk is deleted when the job is completed (when the Start key turns green for the next job).

a. The initial lowering timing of the shift tray is now faster and the stack start time has

been modified to allow the shift tray to return to the top position first.

This is to explain an adjustment to minimize dirty background at the leading edge of the copy due to overtoning in the development unit.

Symptom

Some toner is slightly visible at the leading edge of the copy.

Solution

Please follow the flow chart of the adjustment procedure on the following pages to minimize the symptom.

Please note that since this adjustment is to stabilize the toner amount in the development unit at a lower level to prevent overtoning, some customers may complain about a lighter image in black solid areas, especially at an early stage from installation and for the first several copies every morning. Please adjust the SP modes for the development bias to meet the required level for each customer.

However, there is no problem with text area.

New Factory Settings

To minimize the dirty background, the factory settings of some SP modes have been changed to stabilize the toner amount in the development unit at a lower level which prevents overtoning.

Please refer to the explanation on the following page for the details. Because of the change of the factory settings of some SP modes, black solid areas may

be lighter at installation. This model has a toner recycling system. The toner amount in the development unit is

determined with a calculation including not only new toner but also recycled toner. At installation, the pipe for the recycled toner is empty and it takes 1,000 to 2,000 copies for the first recycled toner to come into the development unit. This means that the toner amount in the development unit is less during the first 1,000 to 2,000 copies after installation and becomes higher after that.

Please adjust the SP modes for the development bias to meet the required level for each customer.
