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 en-
able you to meet customer requirements better, quicker and in a clearly struc-
tured 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 train-
ing 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 in-
complete 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 ad-
equate information so that you can do your work quickly, correctly and with a
continuing sense of satisfaction.
Feedback

may find imperfections and/or errors. Océ would be grateful if you would in-
form ITC (International Training Centre) in Venlo of any errors, imperfections
or suggestions for improvement. You can do this as follows:
