SpinJet 1000
Service Guide
Safety precautions
SpinJet 1000 is intended for use on the large format printer HP
DesignJet 1050C/1055CM (referred to as the printer) only. The instructions for installation and operation of both printer and SpinJet
1000 must be followed.
SpinJet is intended for permanent installation on the above mentioned
printer type. Normal single-sided printing is possible without removing
or tilting down the SpinJet 1000.
SpinJet 1000 is intended for operation with installed top cover and
mounted side covers.
The operator may remove the top cover during a jam removal. Only
specially trained personnel should carry out tasks for test or service
purposes, requiring operation in otherwise open and/or dismounted
condition.
The routines of inspection and replacement of wear and spare parts
must be followed. Always disconnect Power Mains before
disconnecting cables and electrical parts.
Connect SpinJet to Power Mains 100-120VAC or 200-240VAC,
50/60Hz, one phase and earth. Apply a Power Cord according to local
Voltages and Plugs. A UL Listed Power Cord rated minimum 10A,
125V is provided with SpinJet in areas where this apply.

For information on installation procedure: Please see SpinJet Installation
Guide.
For information on specifications, normal use and operation: Please see
SpinJet Operator’s manual.
1.1 Functional test
In order to establish the existence of a possible problem and later the
effect of the corrective action taken, test the SpinJet as follows:
Connect the SpinJet control box to a power outlet.
Switch the box on with the rocker switch. A red light in the button
indicates that the control box is “on”.
Switch on the SpinJet by pressing the power button of the SpinJet
keyboard. Verify that the motors initialise and bring the system into the
“Single” state.
Press the mode button. Verify that the system switches to the
“Double” state and raises the flipper gate.
Install a SpinJet approved paper roll according to the user guide.
Run the test jobs of the software supplied with the product. Verify that
both sides are printed and the required front to back match is achieved.
If the match is inadequate, repeat the procedure of loosening the four
screws securing the printer to the printer base, moving the printer
slightly on its base and tightening the four screws again. Repeat until a
satisfactory result is achieved.

Service guide March 2001 7
Where possible, verify the hypothesis regarding the cause of an
experienced problem by trying to replace the suspect part or system.
Make only one replacement between these tests and go back to the
originally fitted part or system, when there is no effect of the
replacement.
All sensors are using an optical principle, where the effect is that of a
light path being intersected by a moving part or by the medium. All
sensors are equipped with monitoring LED’s with the following functions:
PS01: Green LED on means that the signal is stable and
unambiguous.
Red/orange LED on means light path is cut by an object
(“dark”).
PS02-05: A red LED means, that the light path is not cut by an
object (opposite of “dark”).
These functions serve to help identifying certain sensor related faults
before trying to replace the sensor itself.

2. Wear and Spare Part replacement
procedures
2.1 General
Replacement procedures require
that the SpinJet is mounted on a
printer or supported similarly. In
general replacements require
covers to be removed first.
Further for general reference,
Guide 2 and Guide 5 are identified
in picture below.
In order to maintain internal
accuracy of the unit, the screws
of Beam 1 and Guide 1 should
never be loosened.
Recommended tools:
§ Torx screwdrivers T10, T15
and T20
§ T25 (provided with HP
Printer)
§ Straight blade screwdrivers
(small sizes)
§ Thin blade knife
§ Pair of pliers (pointed)
§ Soft head hammer
§ M5 screw, length 12 mm
min. (provided with the
SpinJet)
§ PIC extractor

5551 066 Timing belt
WARNING!
Always support and lower the
boom (picture) by hand when
loosening and removing timing
belt of motor 3.
Remember to loosen the 3 motor
standoff screws (picture) before
replacement. Reapply correct
timing belt tension according to
below procedures.
Motor 1 and 2
Adjustment of timing belt
5551 004:
With the motor turned off and
all 3 motor standoff screws
loosened apply a load of 2N
near the tip of the screwdriver
engaging the TOP screw and
tighten screw (picture). Then
tighten the 2 other screws.
The load can be provided by a
spring balance or by hanging a
200g mass load (e.g. a stack of
sheets) on the screwdriver.
Make sure the belt is not
transmitting torque during the
procedure.

Motor 3
Adjustment of timing belt
5551 066:
Make sure the belt is not
transmitting torque during the
procedure (lower the Boom to
the bottom position).
With the motor turned off
loosen all 3 motor standoff
screws (inside the side plate).
Move the unit until the timing
belt has no preload and
minimum slack (picture) and
tighten the screws.
Test the tension by turning on
the SpinJet, switch it to the
Double mode and intersect the
beam of PS01. Motor 3 will
now lower the boom until the
Reset-button is activated.
Too much tension gives more
noise and possibly stalling
motor during lowering.
Too much slack will cause the
belt to disengage the teeth of
the motor pulley at a slight load
of the Boom during raising.
Repeat the positioning if
required.

To disconnect motor 2 or 3 (left
side of unit) first disconnect
motor harness at connector PCB
(right side), then pull the harness
just enough to gain access to the
connectors.
Make sure to lower boom before
removing timing belt on motor 3.
Loosen 3 screws on the motor
flange and remove the timing belt.
Replace motor, tighten 3 screws
on motor flange and reconnect
motor harnesses.
Adjust timing belt tension as
described in previous section.

Component safety precautions
Handling:
• Avoid touching the legs,
which are susceptible to
static electricity
• Keep the legs mutually
“grounded” with conductive
material for storing/shipping
Exchange:
Note the position of the half-circle
notch on the body of the PIC: It
should be pointing downwards in
the control box when mounted on
the printer.
Before replacement switch off
power completely by removing the
supply cord. Replace the PIC
using a PIC extractor (tool) as
shown in picture.
Especially if tool is unavailable,
take care to lever out and install
the PIC as parallel as possible,
thus avoiding bending of the legs.
