Basics Introduction - 1

Introduction

The StyleWriter 1500 is a
high-resolution ink-jet
printer. There are some
differences between the
StyleWriter 1500 and the
StyleWriter 1200.

Basics Introduction - 2

Hardware Differences

• The sheet feeder has changed to be compatible with the
new paper feeding scheme that the vendor has
implemented across the product line.

• The plastic cover of the controller and feed rollers has
been changed to match the paper feeder.

• There is no Error LED on the 1500

• No paper output tray

• No internal power supply, external power adapter

Basics Introduction - 3

Software Differences

• Two additional print modes have been added to the
StyleWriter 1500: Fine and Smooth. Fine mode uses 360
dpi resolution and Smooth uses a 720 dpi horizontal by
360 dpi vertical resolution.

Basics Introduction - 4

Color Capability

Two ink cartridges are available for the Color StyleWriter

1500. There is a black-only ink cartridge and a three-color

(Cyan, Magneta, and Yellow) that produces a composite black
as well as color.

The black-only ink cartridge is the same for both the
StyleWriter 1200 and 1500.

Basics Test Page - 5

Online Key

Test Page

Turn on the printer and hold
down the online key for at
least 6 seconds or until the
test page prints.

Basics Test Page - 6

The test pages show the ROM
revision and a test pattern.
There are two different test
pages; one for the three­color ink cartridge, and one
for the black-only ink
cartridge. The black-only
test page is shown here.

Use the test pattern to
determine if the ink jets are
functioning properly. If
lines at the bottom of the
page appear broken,
proceed to the “Printing”
topic in the Troubleshooting
chapter.

Basics Test Page - 7

Demo Test Page Units

The Color StyleWriter 1500
demo unit logic board ROM
contains a unique demo page.
A limited quantity are being
sold for use by Apple
resellers.

Note:

The demo test page
printer may be serviced the
same as a regular 1500,
however, if the logic board
is replaced it will lose the
demo page capability. If that
feature is needed, the unit
should be RMAed to Finish
Goods.

Troubleshooting General/ - 1

General

The Symptom Charts included in this chapter will help you
diagnose specific symptoms related to your product. Because cures
are listed on the charts in the order of most likely solution, try
the first cure first. Verify whether or not the product continues to
exhibit the symptom. If the symptom persists, try the next cure.
(Note: If you have replaced a module, reinstall the original module
before you proceed to the next cure.)

If you are not sure what the problem is, or if the Symptom Charts
do not resolve the problem, refer to the Flowchart for the product
family.

For additional assistance, contact Apple Technical Support.

Troubleshooting General /Initial Startup Sequence - 2

Initial Startup Sequence

1 Plug in printer and press the power button.
2 Logic board is tested (ROM/RAM)
3 Power LED comes on
4 Carriage motor initialization (ink cartridge will move).
5 Motor starts and carriage assembly moves to home position

(slightly to the left of the purge unit).

6 Carriage motor detection.

• Home position detected.

• Maintenance cleaning performed.

7 Paper feed motor initialization.

• Paper feed motor runs.

• Pickup roller and paper lifting plate set to their initial
positions.

8 Ink cartridge check.
9 Printer is ready.

Troubleshooting Symptom Charts /Preliminary Checks - 3

Preliminary Checks

Computer cannot find printer

1 Print out a test page to confirm that the printer is

operational.

2 Verify that StyleWriter 1500 driver is installed in system

Extension folder.
3 Verify that serial cable is connected.
4 Verify continuity of serial cable and replace if necessary.
