This publication is and remains the property of Océ-Nederland B.V. The information it contains is confidential and is solely intended as a personal aid for service personnel in carrying out service activities on the Océ equipment described in this publication.

1 TSM information
Why should you use the Technical Service Manual Océ 7050 ?
The TSM Océ 7050 is one of the tools you will need for your work. It will enable you to meet customer requirements better, quicker and in a clearly structured and accessible way.The TSM provides you with information you will require for installing and carrying out corrective and preventive maintenance on this machine.
At whom is the TSM Océ 7050 targetted ?
This TSM has certainly not been written as a teach-yourself manual. During the Océ 7050 service training course you will learn to use and interpret the TSM in such a way that you can work quickly and efficiently.The service training course also gives you an opportunity to broaden your knowledge on how the machine functions. The TSM and service training course are closely linked. Participating in a service training course without using the TSM is just as incomplete as using the TSM without having learnt how to use and interpret it in a service training course. The compilers of the TSM hope that you will find adequate information so that you can do your work quickly, correctly and with a continuing sense of satisfaction.
Feedback
Naturally, this TSM is always open to improvement. It is not unlikely that you may find imperfections and/or errors. Océ would be grateful if you would inform ITC (International Training Centre) in Venlo of any errors, imperfections or suggestions for improvement. You can do this as follows: This chapter contains a Document Change Request Form (DCRF). Copy this Form and enter any remarks you may have about this manual. Send the DCRF to the Technical Co-ordination department. This department will inform the International Training Centre-Service. The address is: Océ-Nederland B.V.

2 General warnings
We would like to draw your attention to the general warnings, summarized on this page. You will find specific warnings further on in the TSM in the descriptions of operations that have to be carried out in dangerous circumstances.

I
Avoid damaging PBA's via electrostatic discharges. You should wear the wristband, code no. 7991.320 and use the antistatic mat, code no. 7991.322. AVOID ELECTRIC SHOCKS! Switch off the power supply to the machine and remove the mains plug from the wall socket if the machine does not need to be on when you are working on it. AVOID MOVING PARTS! When you remove the panels from the machine, make sure that you do not get your fingers caught between moving parts such as chains, cogs and gear belts. This equipment must be earthed. Always ensure that wall sockets and power switches are easily accessible. A blown fuse does not guarantee a powerless situation. When replacing a mains cable or mains plug, only use components which comply with local regulations.
3 Notation conventions
Note
A "Note" provides information that is essential for a correct functioning of the machine. It may also offer useful advice about its operation.
Warning
A "Warning" provides information that can prevent the product (copy, original, the copier etc) from being damaged.
Caution
A "Caution" provides information that prevents you from suffering personal injury.
Approx.
Whenever a measurement is indicated with the expression approximately or approx., non calibrated measuring instruments can be used.

4 Functional test
After every service visit a functional test must be done:
I I I
Make a copy of a typical original used by the customer. Show the copy to the customer. The customer must agree that the machine is performing according to his expectations and within the machine specifications laid down in this Technical Service Manual.

Error codes
3 General
The errors in the Océ 7050/51 and the Océ 7055/56 can be subdivided into the following categories:
FE Fatal Error
A fatal error is an error in the control mechanism. The correct functioning of the control mechanism is not guaranteed after a fatal error. f.i.: I (EP) ROM defect I RAM defect
MRE Machine recoverable error
Machine recoverable errors are errors in the system and can normally not be remedied by the operator. The operator can only try to restart the machine. In some cases when an MRE is repeatedly detected, a service call will be generated.
ORE Operator recoverable error
Operator recoverable errors are errors that can be remedied by the operator without switching off the machine. Examples of ORE's are: paper path errors, original path errors and cover errors.
WAR Warnings
A warning is a safety mechanism intended for the operator. The machine will operate correctly. The copy quality will deteriorate if no action is taken. In the following table you see these 4 categories and the way the operator can recognize what type of error has occurred:

The purpose of the Service Diagnostic System (SDS) is to support the service technician in identifying the causes of errors and to provide information on the errors themselves. It is also an important tool for adjustments and installation. The SDS tests are sub-divided into the following categories:

7 Measuring the drum current
When your Amp. meter is sensitive enough, it is possible to measure the drum currents.
1 Behind the left cover, you will see a wire connecting the drum to ground. 2 Disconnect the connector of this wire and connect your Amp. meter between
the drum and ground.
3 According to the table below you can now measure several drum currents. Current SDS test Value

Drum handling
The organic photoconductor drum (OPC drum) is very sensitive to light, temperature, and corrosive gasses. Please observe the following cautions when handling the OPC drum:
I I I
I I I
Never expose the drum to sunlight. Never expose the drum to excessive light. Never touch the drum surface with your bare hands. When the drum surface has been touched with bare hands or when it is dirty, wipe it with a dry cloth. Store the drum in a cool and dry place away from heat. Handle the drum carefully because the OPC layer is thin and easily damaged. Never expose the drum to corrosive gasses.

Note: The air handling is very essential for the correct functioning of the Océ 7050. Sealing is essential due to the sensitivity of the fuser to convection.
The air handling has the following functions:
1 It keeps the ozone emission within specs. 2 It keeps the ozone concentration near the drum below a specific value.

Adjustments
1 Exposure maximum level
First we have to adjust the voltage at which the lamp will have its maximum power. This voltage is indicated by the manufacturer of the power supply. When the lamp gets hotter, it produces more light with the same input power. Therefore we cannot set the voltage at the wanted value, but do we have to do the adjustment as follows:
1 Put a folded, white A1 sheet on the original glass. 2 Connect a multi-meter between TP1 (EXPSE) and TP2 (GND) on the exposure

1 Exposure control
The main controller 22PBA01 sends a signal for the "required light intensity" to the exposure supply 04PBA01. The "actual light intensity" is measured by the exposure sensor 04PBA02. These two values are compared on the exposure supply 04PBA01. According to the result, the voltage for the exposure lamp 04E1 is adjusted. Also the main controller 22PBA01 is "informed" about the "actual light intensity" for control reasons.
