Non-Glossy Streaks Due To The Peeled Off Tape On The Separation Plate - Canon imagePRESS C850 Series Troubleshooting Manual

Non-glossy streaks due to the peeled off tape on the separation
plate
[Symptom]
On the main body whose Countermeasure Cut-in Serial Numbers in Factory is earlier than the following number, non-glossy
streaks [a] image may occur with high gloss media or heavy media (200g or more).
The arrow indicates the paper feed direction.
[Cause]
The separation plate [1] in the fixing assembly [A] comes in thick and thin types. The tape affixed to the thicker separation plate
[1] comes off [a] from scuffing, then the fed paper comes in contact with the peeled off tape and leads to the above mentioned
symptom.
The arrow [b] indicates the paper feeding path.
[Service work]
As a countermeasure against the aforementioned symptom, replace the separation plate with the thinner type that reduces
scuffing of the tape even when a high gloss or heavy media is passed through.
To make this feasible, newly assign the fixing separation unit with the thinner separation plate, inner paper delivery assembly
and fixing base assembly as service parts respectively. The other type with thicker separation plate is also going to be newly
assigned as well. As to the newly assigned new type inner paper delivery assembly and the fixing base assembly, their fixing
separation units are removable. The fixing separation units of the old types are not removable.
If the shape of the inner paper delivery assembly is as shown in the photo [A], replacing the fixing separation unit only is possible.
The photo [B] shows the shape of the old type inner paper delivery assembly.
