can you reduce dpi settings and still get a good enough image to please the customer? sounds like it is set to max resolution. just something simple to try. though customer will probably complain quality is no longer what it was before. i agree with what was already stated. sounds like to me they need an actual production copier with a fiery system. and being they are always on a budget.

This is a very mis-understood process so let me clear this bit up.

First, all page adjustments max out at +/- 3mm (that's all you get, 6mm total movement range. Each increment equals .1mm of movement so small adjustments are difficult to detect. These are hardware adjustments not effected by software so print and copy results should be the same.

U034 is the REGISTRATION adjustment as to where the image lands on the page. If you adjust this it will increase the erase margin by moving the image. So registration is incorrect, and it has to be adjusted for duplex as well for F-R alignment.


U402 is Print Margin, but it actually means 'Erase Margin' and this doesn't mean only printer jobs it means everything which is output from the print engine, including copies. It controls how much of a properly aligned image is removed from the edges.

A combination of the 2 may give better results.

'Print Job' margins are controlled by the application and driver, but for jobs with no driver code for margins, they are changed by FRPO A1 to A4 and somewhat by the R3 parameter.

A trained and proactive user would intelligently add to the margins when printing from their application to prevent problems with heavy fill/edge-to-edge prints. (BC nod)

The new fuser is a good plan as jammed paper can wind up out of reach under the rollers and interfere with the thermistors' sensing.

I like it. Thanks for sharing.

I have to disagree with the u402 it definitely doesn't affect everything. I have a edge to edge pdf I use to test and you can put u402 to the max and the print margins don't appear to have changed.

Pretty sure it doesn't affect iPad printing as well. I have many schools that just print pictures and nothing changes the margins other than u034 trickery but it's very awkward to get right.

I'll have to check it but I've done it many times now on the 52 and 53 series machines. I'd love to be wrong as it's very easy to set u402.
