Custom printer driver for Xerox 7760 needed.

We have a Xerox Phaser 7760 with a finisher (folds and staples).

For our in house printing we use thin coated paper, but the factory drivers won't allow paper that is specified as coated to go to the folding and stapling unit.   The finisher handles the coated paper fine, as long as you specify plain paper, but the print quality of coated paper suffers if you specify plain paper in the setup.

I need a driver that will accept a coated paper setting when folding and stapling.  We would pay for the driver or would appreciate help learning how to write one ourselves.

If you are using a Postscript driver it may be possible to edit the PPD file.

The PPD is a text file that telss the drive what the printer can do, and the commands to do it. If you go through it you may be able to add the coated paper to the Finisher section of the PPD. You will need to do a full reinstall after modifying the PPD.

hdhondt,

I think you are on to the solution, but I'm not smart enough to apply it.

I have studied the PPD file and Adobes' PostScript Printer Description File Format Specification

It looks like *UIConstraints: could be used to limit the access to the fold and staple finish functions, but I can't find any use of *UIConstraints: being applied to coated paper.  Nor can I find a constraint that limits finishing work to plain paper.

For any brave soul who would care to look at it, here is the finisher and booklet making set of constraints.   (The whole PPD is also attached.)

A solution would be greatly appreciate!

*% Finisher Constraints


*UIConstraints: *XRXOptionFinisher False *XRXPunching 2_Holes
*UIConstraints: *XRXPunching 2_Holes *XRXOptionFinisher False
*UIConstraints: *XRXOptionFinisher False *XRXPunching 3_Holes
*UIConstraints: *XRXPunching 3_Holes *XRXOptionFinisher False
*UIConstraints: *XRXOptionFinisher False *XRXPunching 4_Holes
*UIConstraints: *XRXPunching 4_Holes *XRXOptionFinisher False

*UIConstraints: *XRXOptionFinisher False *XRXStapling Front
*UIConstraints: *XRXStapling Front *XRXOptionFinisher False
*UIConstraints: *XRXOptionFinisher False *XRXStapling Dual
*UIConstraints: *XRXStapling Dual *XRXOptionFinisher False
*UIConstraints: *XRXOptionFinisher False *XRXStapling Quadruple
*UIConstraints: *XRXStapling Quadruple *XRXOptionFinisher False
*UIConstraints: *XRXOptionFinisher False *XRXStapling Rear
*UIConstraints: *XRXStapling Rear *XRXOptionFinisher False

*UIConstraints: *XRXOptionFinisher False *XRXStapling Fold
*UIConstraints: *XRXStapling Fold *XRXOptionFinisher False

Sorry Ron, but I don't see any attachment. If you can post it I'll have a look to see what I can find.

Sorry, hdhondt,   I didn't notice that the PPD file was rejected for upload, since PPDs are not on the accepted file type list.

I changed the extension to TXT and attached it, herein.

Thanks!

I had a look through the PPD and could not see anything to change the printer's behaviour.

It would appear that the printer restricts itself to plain paper for the collator/stapler. While it is possible to change the PPD, to fool the printer into thinking coated paper is the same as plain paper, that would apply to all printer functions, not just the collator. In other words, it would then also change the printing settings (fuser temperature, etc). To put it another way, it would behave exactly the same as if you selected plain paper in the driver.

It appears that Xerox have built this into the printer's hardware, possibly to avoid other problems like jamming, etc.

We currently print and finish the coated paper using plain paper settings but the quality is not good and if we print many pages in a row, the ink flakes.

The paper handling of the coated paper is just fine, though.  It folds and staples as good or better than plain paper.  There is no reason to restrict it.

I've asked Xerox for a solution and offered to pay for it, but they aren't interested.  It is a sever limitation of an otherwise great printer.

Thanks for your help!    I guess I'll continue to look for another way around this problem.

If you can locate a service manual of the machine read on :

The difference between paper settings in the driver always correspond with machine settings and have a lot to do with fuser temperature for instance.  You could lookup the service manual of the machine and find the maintenance login to enter the machine settings.  

Then go to paper settings and have a look at the temperature, leading edge registration,... settings for the coated paper you prefer to use and write them down EXACTLY.

If you can find another paper type in the driver that is also supported by both finisher and stapler, go in the maintenance again, and "copy" all the settings of the coated paper onto that type of paper.  This way the machine has the exact same internal process for handling the paper :

fixing temperature
speed
registration edges

so the print quality will be fine.  DO NOT change the setting for normal paper as you will obviously run in to problems doing normal print jobs.  i would then install the xerox machine a second time - rename it specialprinter - so the driver settings only apply to that specific printer and your printer driver only

@Geert That's not a bad idea. However, as the printer appears to only accept plain paper in the finisher, changing the settings for another paper type will not help in this case - unless the paper type modified is normally fused and otherwise treated the same way as plain paper. Some possibilities for that include:

Letterhead
Colored Paper
Preprinted

Ron, you can test the feasibility by checking whether the printer will accept Letterhead in the finisher. I assume it should, as you may want to staple a document with a Letterhead page as the first page.

I found a Service Manual for $9.50 T http://www.anyservicemanuals.com/downloads/xerox-phaser-7760-service-manual-parts-list/ . I had a look through the table of contents and could not see anywhere to change fuser settings.

You can also see if fuser settings are available from the front panel menu. It's possible they are accessible under the Service Tools menu (in Troubleshooting). The User and Administrator manual say almost nothing about the menu, so I cannot tell you what's there.

Herman,

I bought the manual -- all 900 pages!

I haven't been able to find settings that will let me hack the paper / fuser settings, but there is a lot to look at and it is a long document.

Do you have suggestions for key words I can search for?

Thanks!

As I said, I could not find anything when I looked through the table of contents, so it may not be in there. As you have the full thing, try searching for "fuser", or "temperature". There will be lots of entries for both, especially "fuser"...

Have you looked through the Service Tools menu yet?

Sure can, Geert!

I had to break it into two files to stay under the 50 meg limit.

Sections 1 through 4 are attached, herein.

Page 4-108 (pg 550 in the first PDF) has a section
ADJ 9.16 Calibrate for Paper
Purpose
Calibrate for Paper is used for adjusting the printer for various paper types and environmental conditions. You may need to readjust the printer when you change brands, paper types, or the temperature or humidity changes significantly.
Procedure
NOTE: Ensure to load 8 x 11 media (LEF) in Tray 1 (MPT) to perform this procedure.
1. Go to the Printer Menu. Scroll down the menu to find Troubleshooting and press OK.
2. Select Print Quality Problems and press OK.
3. Scroll down the menu to find Calibrate for Paper and press OK.
4. Select Calibrate for Paper Pages and press OK.
5. The printer prints 9 Calibrate for Paper pages.
6. Follow the instructions on the Calibrate for Paper to perform the procedure.
Note that it does not mention different paper types, just 9 calibration pages and then "follow the instructions on those pages".

Try that and see if it lets you adjust for different paper types. If it does, adjust Letterhead until it prints fine on your coated paper. You can access it from the front panel, via Printer Menu > Troubleshooting > Print Quality Problems > Calibrate for Paper > Calibrate for Paper Pages (see pg 433).

BTW, have you checked that the finisher accepts Letterhead? If it doesn't, this entire exercise is probably to no avail.

Ahhh, Herman, I think you're on to something.

Even if the finisher won't accept letterhead, I may be able to find another paper, besides plain, that will work.  

BTW, the finisher will punch coated paper, it just won't fold it.

I'll try this and get back to you.

Thanks!
