Phaser 140 hints and tips
Paper pick problems
Users must fan the media before putting it into the input tray. This will solve
many paper-picking problems.
Media curl (before printing)
If you are using coated paper, glossy paper, back-print film, or transparencies,
use only Tektronix media.
Tektronix has tested a wide variety of media with the Phaser 140. The media
offered by Tektronix for the Phaser 140 has been found to provide the best image
quality, drying time, and resistance to curling. However, in some environments
the media may curl. The media specifications call for no more than 1/2 inch of
curl, when the media is laid on a flat surface.
If media is curling too much, try another package of media and place the
original package in a clean environment. The original media will usually lay flat
after it has become acclimated to the environment.
Output tray capacity
■For prints with 100% coverage, no more than one sheet at a time
should occupy the output tray. This is because the ink may not have
dried before a second print is ejected into the tray, resulting in
smeared prints.
■For prints with a full page of 12-point text, no more than 15-20 sheets
should occupy the output tray. This is to ensure that the paper path is
clear for ejecting subsequent prints.
Printer squeaks while printing
Squeaking indicates that oil is needed on the carriage transport rails. The
carriage transport rails are the two rails that support the carriage (1).
1

15
Phaser 140 Service Supplement
1. Open the cover.
2. Apply a few drops of oil to each rail (use FLOIL; Tektronix order
number 006-7436-00).
3. Execute any printer operation that will cause the carriage to move
across the rails and distribute the oil. For example, printing a test
print will do this.
Invert the image before printing on back-print film
Images should be printed in reverse, or mirror-image, for proper projecting on
back-print film, Refer to your application’s documentation for complete
information on printing reverse or mirrored images.
If black is not printing dark enough on back-print film
To print darker blacks, try selecting either Glossy Paper or Transparency as the
Media Type when printing on back-print film.
■Macintosh driver
1. Select Print from the File menu.
2. Click the TekColor button in the Print dialog box.
3. Select either Glossy Paper or Transparency as the Media Type in
the TekColor Options dialog box.
■Windows driver
1. Double-click the Printers icon in the Control Panel.
2. Choose the Setup button in the Printers dialog box.
3. Choose the Options button in the Setup dialog box.
4. Choose the Printer Features button in the Options dialog box.
5. Select either Glossy Paper or Transparency as the Media Type in
the Tektronix Printer Features dialog box.
■Printer’s front panel
1. View the SET MEDIA TYPE menu.
2. Select either glossy paper or transparency.

16
Phaser 140 Service Supplement
Loading back-print film
Select the back-print film setting in your computer’s driver. Refer to the Phaser 140 Color Printer User Manual for more
information on printing from a Macintosh, a PC, or a workstation.
1. Move the paper selection lever
toward the back of the printer.
2. Open the printer’s cover and move
the paper thickness lever (near the
printhead) to the down position.
Close the cover.
3. Load a stack of back-print film into
the printer, making sure that the
stack does not exceed the limit mark
on the right side of the input tray:
a. Adjust the paper guide to
the width of the stack of
back-print film.
b. Turn the stack of back-print
film so that the film side
faces you.
c. Insert the glued ends into
the printer.
d. Slide the back-print film
into the printer until it stops.

Memory SIMM installation
The following topics describe memory SIMM installation for the Phaser 140.
Three types of memory SIMM are available, as shown in the following table.
Static electricity precautions
■Leave the printer plugged into its power outlet. This preserves a
ground path for static discharges.
■Touch the printer's bare metal frame often to discharge static
electricity from your body.
■Handle the circuit board(s) by their edges only.
■Do not lay the board(s) on a metal surface.
■Make the least possible movements to avoid generating static
electricity.
■Avoid wearing wool, nylon or polyester clothing; they generate static
electricity.
Memory installation
1. Disconnect the host interface cables from the rear of the printer.
2. Remove the two screws securing the image processor board to the
printer.

hole on each end of the RAM SIMM. Also, a pawl on each end of the
connector latches around each end of the RAM SIMM to lock it in
place.
6. Slide the image processor into the printer and secure it in place with
the two screws removed earlier.
7. Reconnect the host interface cables. Turn on the printer and print the
startup page. The startup page lists the amount of installed RAM.
Refer to the user manual for instructions on printing the startup page.
Note Make sure that an 8-Mbyte memory SIMM is installed in the first slot
nearest the back panel. This slot must be filled first.

Phaser 140 Service Supplement
Ethernet card installation (F-kit 4686FP1;card part number 671-3357-00)
This instruction sheet provides details for installing an Ethernet card onto the
printer's image processor board. The installed Ethernet card gives the printer
the ability to communicate on EtherTalk and Novell networks. To enable the
card for TCP/IP network communication (a separately purchased
customer-installable option — order kit 4680FP2). After installing the Ethernet
card, refer to the topic “Enabling TCP/IP with the downloadable software key”
at the end of these instructions.
The software included with this upgrade is expressly incorporated in the
LicenseAgreement for Software and Typefont Data shipped with your Tektronix
printer.
