Printing
The printer accepts raster-oriented data in the format of HP RTL. In this mode, printing begins immediately after
the first complete line of HP RTL data is received.
There are many Raster Image Processors (RIPs) which convert Postscript or CGM to HP RTL. When choosing a
RIP or a file format converter for output to the printer, make sure it has the features you need. (Contact your
Xerox distributor or dealer for an up-to-date listing.) If your applications do not support HP RTL, there are several
software utilities available to convert various raster file formats (TIFF, GIF, BMP, etc.) into HP RTL.
Obtaining quality results
You have probably seen a demonstration of your printer's capabilities or sample output.
If so, you are aware of the superb color graphics which can be obtained. Note, how-
ever, that to obtain high-quality results, you must consider several factors. Follow the
simple guidelines in the sections that follow to obtain excellent results.
Use the right inks and media
Your printer features six thermal ink cartridges with 640 jets each. Reservoirs hold
up to 700 ml of ink. You can print with six colors of ink (CMYK, MLand CL)
which create a combination of color gamut and smooth tonal gradations for your
most challenging applications. Note: in the calibration patterns, the MLand CL
cartridges are referred to as M1 and C1.
Ink sets for the 8142/8160 include dye and pigment offerings. Xerox ink sets
offer optimized, matched and quality ink solutions. Every ink formula is
scientifically designed to obtain the best performance possible in the printer
for which it is created. Extensive testing under a variety of extreme
environmental and production conditions ensures the ink performs consis-
tently.
When Xerox inks are used with Xerox Wide Format Inkjet Media, you receive industry-leading
performance guarantees that ensure customer satisfaction.

Caring for your ink and cartridges
• Handle cartridges only on the plastic areas.Touching the copper electrical inter-
connect or the inkjets can damage the cartridge.
• Use only dye or pigment ink intended for this printer. Do not mix inks.
• Do not shake ink refill containers.
• Store ink and cartridges in the same environment as the printer whenever possible.
• If you remove a cartridge from the printer, do not leave it exposed to the air for an extended period because the jets
may clog. Replace the original tape on the jet plate. Place the cartridge in a cartridge garage or sealed plastic bag and
store it in a closed area at room temperature. Keep it out of direct sunlight.
• Open new cartridges only when you are ready to install them.
• Use only Xerox-brand ink refills and cartridges.
•When you receive a "Low Ink" warning, there is approximately 15-20 minutes of printing time remaining before
the intermediate reservoir runs out of ink.
Note: When an ink bottle is removed, you have 30 seconds to put in another bottle before the printer senses the
bottle's absence and places the printer in Pause mode.
Choose the right media
This printer is designed to print on a wide variety of media including photo gloss, backlit film, matte, self-
adhesive vinyl, canvas, banner tyvek, and more. Refer to the list of compatible media included with your
printer.

Reference Guide 8142/8160
Caring for your media
Store media in its original packaging in a cool, dry area until you are ready to use it. The
environment should be stable; i.e., no extremes of heat and cold, and non-condensing
humidity. If conditions are outside the operating ranges recommended for the printer, allow
the media to acclimate in the operating environment for at least 48 hours before using it.
If you remove a roll of media from the printer, be sure to store it in a manner which
keeps it clean and dust-free. Ideally, you should return it to its original packaging for
storage.
Print on the correct side! Roll media is wound with the printable side out.
Handle with care! Handle your media carefully to avoid creases, scrapes, and
tears.Avoid crushing or damaging roll media edges.
Caution! Some medias use an adhesive to adhere the end of the media to the
core. This adhesive can transfer onto rollers in the media feed path. Abuildup of
this adhesive can cause banding and other imperfections in your printed output.
To avoid this, it is recommended that you always cut the media before the end
of the roll.

Loading media
The procedure for loading media is shown in the Quick Reference Guide. If you are using paper rolls with a core
diameter of 3", it will be necessary to install a core adapter on the roller before installing the roll of media as shown
below. Be sure to orient the media as shown below.

Using the second feed roll
The takeup roll can also be used as a feed roll. If you use the takeup roll as a feed roll, you cannot use the takeup
system. If you want to use the takeup roll as a feed roll, set the printer to ROLL2 by pressing Setup Menu/
Paper Options Menu/Supply Type/Roll2.
Loading Roll Media Using Roll2
Caution: When using the ROLL2 option, the media may have a tendency to curl inward under the bottom roller.
This could block the media sensor and prevent the feed roller from feeding media. Make sure you keep the
media turned outward, away from the media sensor.

Using the takeup roll
The takeup roll allows unattended printing by automatically winding printed media onto a core. In this mode, the
automatic cutter is disabled. When using this option, be sure that the media sensor on the printer's right leg is not
blocked.
Depending on the ambient humidity, temperature, and amount of ink coverage, you may want to turn on the heater
and/or set a dry time as described in Chapter 2.
Replacing the cutter
A cutter located in the ink cartridge carriage cuts roll media. The printer is shipped with the cutter installed. Use
the following procedure to replace the cutter, when necessary.
! Be careful when handling the cutter to avoid injury.
! Cutting media with a worn cutter can cause the media to jam and create a ragged cut line. Replace the
cutter to avoid this condition. Do not cut media on the printer with an external knife, as you could
seriously damage the platen and void the warranty.

To install the cutter
1 Press Utility Menu/Access Cartridge to move the carriage out from the service station.
2 The cutter fits into the left side of the carriage. To remove a used cutter, push the cutter lever down and pull
it out. Install the new cutter by pushing it into the slot until it clicks into place.
3 Press Utility Menu/Access Cartridge to move the carriage back into the service station. This ensures that the
cutter blade is in the home position.
Choose the correct printing mode
By choosing from a variety of color, quality, and resolution modes, you can make choices between drawing quality,
colors, and speed. When printing images with large areas of color, always choose one of the enhanced printing
modes (High Speed, Productivity, Fine, Enhanced, or Ultrafine).
Use the right software
The quality of the software driver or the RIP can be very important, especially when printing continuous tone
images. Error diffusion or stochastic screening algorithms can yield photo-like images, even when these images are
scaled to full size. Software without advanced imaging features may produce images which are grainy when
enlarged.

Basic calibration
Preparations
To prepare for basic calibration you must activate the dryer system. This allows the platen to expand to reach
normal operating temperature.
Note
If the platen were allowed to remain cool for the procedure, the measurements and adjustments would be inaccu-
rate once the platen expanded during normal operation.
Wait at least 5 minutes after completing steps 1 and 2 below before proceeding with the Line Length Test in the
next section.
1. Set dryer to 4(Low Heat, Fans). At the control panel select Setup Menu/Dryer Menu/Dryer Setting. Select
Next or Prev to a setting of 4 and press OK.
2. Activate the dryer. At control panel select Utility Menu/Service Menu/Diagnostics Menu/Accessory Menu/
Dryer Status. You will notice T1 and T2 (temperature sensors) will begin to slowly climb to a target value of
40°C (104°F).
3. Ensure that both rear paper guides are not touching media edges – 2.5 mm (0.1") offset, minimum, on both
sides. This is very important as media drag may occur at either the left or right sides causing left or right side
micro-banding. Also ensure that the media is not rubbing or ‘climbing’ over guides at any time during
printing.
