HP Designjet 9000s Series Printers Service Manual

Inks used in the printer and liquids in the HP Cleaning and Maintenance kits contain an organic solvent (ethylene glycol monobutyl ether acetate, CAS No. 112-07-2). Observe all local, state, and federal regulations related to the handling, use, storage, and disposal of organic solvents.

Avoid contact between ink and skin, eyes, and clothing.

 Immediately wash skin with soapy water.  Remove clothing soaked with ink from contact with skin.  Use an approved eye wash station if ink is splashed into

eyes and consult a doctor if necessary.

 If an approved eye wash station is unavailable, flush

eyes with cold water and consult a doctor if necessary.

Be sure the printer is well-grounded. Failure to ground the printer may result in electrical shock, fire, and susceptibility to electromagnetic interference.

Ink and fluids used in the Cleaning and Maintenance Kits are combustible. Do not use or store within 8 meters (25 feet) of open flames, sparks, or other sources of ignition.

Switch power OFF, remove the power cords from the electric outlets and allow the printer to cool before attempting to remove any panels or covers. The printer contains high voltage and hot components. Removal of panels or covers may result in exposure to electric shock and burns.

Do not allow metal or liquids (except those used in HP Cleaning and Maintenance Kits) to touch the internal parts of the printer. Doing so may cause fire, electric shock, or other serious hazards.

When shutting down the entire system, always turn OFF the printer switch as well as the heater switch (breaker).

Use only an HP Waste Ink Bottle. The bottle must be installed according to instructions or waste ink may overflow.

An HP Waste Ink Bottle must always be installed before turning the printer ON. Automatic and manual service cycles produce waste ink that must be contained in an HP Waste Ink Bottle.

Always use both hands to remove and carry an HP Waste Ink Bottle.

Keep the HP Waste Ink Bottle upright. Do not place on tables or shelves where it could fall.

HP Designjet 9000s Series Printers Service Manual

Waste ink is combustible. Keep an HP Waste Ink Bottle containing waste ink away from open flames, sparks, or other sources of ignition.

Never store waste ink in a glass container.

Never pour waste ink into a container filled with other chemicals.

The HP Waste Ink Bottle contains organic solvents and must be disposed of in compliance with all local, state, and federal regulations.

Always securely replace the cap on a full or partially-full the HP Waste Ink Bottle after removing it from the printer to prevent ink spills.

HP Designjet 9000s Series Printers Service Manual

Treat any media, paper, used cleaning and maintenance supplies, and wipes soaked with ink as combustible materials. Handle and dispose of properly.

Do not clean the printer with benzene or paint thinner. This may damage the paint.

Wipe the printer clean with a soft cloth. A cloth moistened with a neutral detergent may be used. Do not allow liquid to enter the printer. This may create risk of fire and electrical shock and cause a malfunction.

Never touch the printhead nozzles. They can be easily damaged or clogged.

Do not touch heater surfaces in the paper path. This may cause burns. Take care when touching printer components near the heaters.

HP Ink Cartridges must be installed before the “Install By” printed on the cartridge. Use of the Ink Cartridge 3 months beyond the “Install By” date may cause deterioration in print quality or a printer malfunction.

Do not separate the cap from a new HP Waste Ink Bottle. The cap is needed to properly seal the HP Waste Ink Bottle for disposal.

The level in the HP Waste Ink Bottle should be checked by visual inspection to prevent overflow. If the waste ink level is above the indication line, the bottle must be replaced with an empty HP Waste Ink Bottle.

The use of safety glasses and gloves is recommended when performing cleaning and maintenance operations.

Guide to Troubleshooting the Printer

Introduction

This chapter will guide you through the relevant steps to take when troubleshooting the Printer.

Troubleshooting System Error Codes

Chapter 2 - System Error Codes contains a list of system error codes and their respective descriptions and recommended corrective actions. Only try one recommended action at a time and check if the error code has disappeared.

If you have an error code which is not documented in this Service Manual or you have an error which you cannot resolve, then report the error to the HP Response Center or the nearest HP Support Office. When reporting the error, have the following information ready:



Model and Serial Number of the printer.



Which firmware revision the printer is using.



The complete error number.



The System and History Prints

 Which software application the customer is using (name, version, etc.).

Whenever an Error Message is displayed, you should try to switch the Printer Off and then On again to see if the error disappears. If the error disappears, there is no need to troubleshoot the Printer any further.

Performing a Service Test on a Failed Assembly

If possible, always perform a Service Test on the component/assembly that you are about to replace, just to make sure that is the actual component/ assembly that has failed.

If the test on that component/assembly passes, you should NOT replace it.

For information on the Service Tests and how to use them see Chapter 4 - Maintenance Mode.

Troubleshooting

Performing the Necessary Service Calibrations or Adjustments

Is the printer calibrated or adjusted correctly after replacing a component? For information on the Service Calibrations and Adjustments and how to use them, see Chapter 5 - Adjustments and Calibrations.

Remember that certain Calibrations or Adjustments are required even if an Assembly has been disassembled to gain access to another Assembly or Component.

Solving Print Quality Problems

Whenever a Print Quality problem appears, it is advisable to print the Test Print to help diagnose the problem. The Test Print will help you differentiate between possible Printhead errors or mechanical problems. For information on solving Print Quality problems see Chapter 6 - Print Quality.

The Printer does not Power ON

1 Check that the power cord is connected correctly to the Printer and to the

Power Socket.

2 Check that the Power Switch on the BACK of the Printer is in the ON

position.

Special Power On Procedure

When turning On the Printer, the Printer will follow the internal initialization process, turning on the different systems and making the necessary system checks. In order to troubleshoot the Printer the following Power On options are available:

1 Press the Cancel key and Power On button - This will allow you to skip the

system check of the Printer.

2 Press the Cancel and Shift keys and Power On button - This will allow you

to skip the error recovery check of the Printer. You will be given the option to enter the Maintenance Mode in order to troubleshoot the Printer by entering

a password:

 This option is useful if you want to perform the following:

– Ink purging without installing media. In a normal power On situation,

the Printer cannot function without the media loaded.

– Recovery of a damaged NVRAM. By powering in the special power

On situation, the NVRAM can be recovered by entering the Maintenance Mode and by performing the necessary steps to recover the NVRAM.

System Error: System Error 1180: Capping Motor Error

Problem

Capping Motor over current is detected.

Description:

Corrective Action: Try the following:



When the ambient temperature is very low, the Pump Motor Tube becomes hard and the load on the Capping Motor is increased. Make sure that the

Printer is in an environment where the temperature is not below -10

higher than +85



The Capping Station has a Torque Limiter for up and down operation so

that the Capping Station does not experience any over current.



Apply grease on the shaft of the Capping Station Gear so that it helps with rotation.



Enter the Motors Menu (in Maintenance Mode) and open Solenoids L and R. Access the Pump Motors and check whether the Motor Drive Circuit and Motor work correctly by manually rotating the Motor. When the home position is set to "0", it is clear that the home position has not been adjusted and that capping is not available.



Make sure that the Capping Station cables are connected correctly and are not damaged
