Your smallest margin looks exactly right (about 4mm), so the issue is the file submitted is not set to be centered in your case.
Can't help you with Corel, too rare to support, export the job as pdf and print that and by default, Adobe Acrobat/Reader will center the output to the page.
Our Phaser 8560 has also just developed this problem.
It prints consistently, well off centre. This is through different PCs, different software, different trays and even applies to the printer's own test pages.
I have been through the printer settings and can't see margin altering settings that I would expect?
I have been through the Phaser manuals, I can't see a facility to reset or change margins.
Any help or thoughts would be greatly appreciated,
Do internal prints out of the machine also produce this "off center" effect? For example, the graphics demo page would be a good full coverage document to print. If this is off center, then you could be 100% certain its not application related, and more likely machine registration related.
I have now been told (by technicians and a manager) that this problem is inherent in the 8560 as it ages. Again, I say my 8560 is only 2 years old, with low print count. Regardless, the specs state an allowable 5mm margin all around, but no cautions that this could change.
I can't seem to get them to understand that it's not (primarily) that the right margin is wider now. I can compensate for that; however, I can't compensate for the fact that the document prints off-center, regardless of margin settings. I am a graphic designer, and this problem and lack of resolution is totally unacceptable.
Mac. Regardless of paper, regardless of paper tray, regardless of set margin in document, document prints off-center, leaving a wider margin on the right. My previous post states that the technician did not know how to correct this. Tray 2 was replaced, but problem still exists. As a graphic designer, this is a major problem for me.
Not only the above problem, but now it randomly prints post script code. I have wasted so much paper and ink because you never know when this will happen.
Some more info would be useful. What Size paper? Is this a Mac or Windows PC? IF Windows, are you using the PS or PCL Driver?
The PS driver will produce a page with the minimum Hardware margin of 5mm on standard page size like Letter, Legal, Statement all around (plus or minus 1 mm due to paper feed fluctuation). Envelopes produce larger Margins. Check the 8680 Support page and search for Margins for more info.
Hope this Helps.
