Troubleshooting
Troubleshooting 89
3.1 Troubleshooting system error codes
The HP Designjet L65500 Printer automatically detects problems with the printer system. Whenever a
problem is detected, the Front Panel shows a system error code that allows you to identify the failing
functionality and to proceed with the appropriate troubleshooting procedure.
Nearly every possible problem with the printer will be automatically detected for troubleshooting using
the system error code. Use the following list of system error codes to locate a description and the
procedures needed to further diagnose and resolve the problem.
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 (Note below). Check firmware in Utilities / Statistics /
Code rev.
• The complete error number.
Troubleshooting
• The Service Configuration Print.
• The Current configuration sheet.
• Which software application the customer is using (name, version, etc.)
NOTE: When reporting the System Error Code, make sure that you supply the full Error Code
and the firmware version.
Understand system error codes
System error codes result when the printer automatically detects a problem, and are used to make
troubleshooting easy.
System Error Codes display on the Front Panel (but can also be seen on the Information Page) and are
expressed using the XX.YZ. or XX.n:YZ.m formats.
• XX: Service Part/Subsystem where the failure has been detected.
• n: Service Part Index (if more than one used in the product) - Optional
• e.g. Identify the Ink Supply (color and number).
• Y: Who should perform the action (1 digit) - (0 for User or 1 for Service Engineer).
• Z: Action to perform (1 digit).
• m: additional actions/information to consider (1 digit) - Optional.
• e.g. Non-authorized ink was detected, PM was triggered or Printhead in/out of Warranty.
The YZ portion of the error code tells you the recovery action, if any, and who is allowed to perform the
recovery action.
Resolve a system error code
Some of the error codes are continuable, which means you can press Enter on the Front Panel and
continue working with the printer. Non-continuable error codes do not allow you to continue working with
the printer.
NOTE: Even though the customer can continue working with a Continuable Error Code, an
on-site visit should still be planned to troubleshoot the problem.

an electrical failure inside the PCA and the PCA may require replacement. Before proceeding
with the PCA replacement, check all ink supply connectors and ensure pins are ok with no obvi
ous short circuit in the connections. Check the power feed to pumps and electrovalves and
ensure there is not short circuit between power and ground at the component side. Repair any
parts that have been found to have failed.
24V are not arriving from the cable (note: ensure 24V activated in the printer). If 24V are arriv
ing, ensure the connector and pins are correct, replace ISS PCA
Board. J19, Pins 1 (+24V) and 6 (GND). If power is not leaving the Main interconnect (note
ensure 24V activated in the printer) ->The main interconnect requires replacement. Before
replacing the PCA ensure that the output line does not have a short-circuit, if the output is leav
ing the Main Interconnect, check the arrival of the current to the ISS Board on the connector
side, localize and repair any short-circuits before replacing the PCA. If the LEDs are off, check
the power output in the Main Interconnect Board with a multimeter.

Troubleshooting
PID no power up with single phase
1. Check PID displays are ON (powered single phase), Ensure single phase power arrives to the PID
controllers (refer to
Power fuse blown, or power fuse bay has failed or is not correctly closed.
2. Open e-cabinet ensure the power fuse bay is correctly closed
3. Check the Fuse blown indicator in the power fuse blocks (FH4&FH5, top red indicator square must
be RED, we also recommend opening the fuse bay to ensure no fuses have been triggered, note
power off e-cabinet to perform any operation inside), If fuse is blown, replace as appropriate. Note.
Before replacing the fuse make sure there is no short-circuit in the line of the fuse blown with GND
and also with other lines. Repair the identified short circuit that caused the failure.
How to check the lines in the power modules:
Measure the resistance in the output connections (A2-B2-C2) of the power modules between these
points and ground (any ground reference in the printer will do, such as the back plate of ecabinet),
and the value should be infinite. Measure also the resistance value between (A2-B2, A2-C2, B2-C2),
the value must be approximately 32 ohms (+/- 2 ohm) for the star configuration and for the delta
configuration 16 ohms (+/- 2 ohm).
PID Controllers not correctly configured
4. Check PID controller line output 2 is active. If it is not active, check configuration of PID controller
page 530. If configuration is OK replace the PID Controller
page 73. If power arrives and the display is Off, replace PID Controller

printing environments. Lighting, line faults, or the power switching commonly found in machinery in
factory environments can generate line transients that far exceed the peak value of the applied volt
age. If not reduced, these micro-second pulses can disrupt system operation. In these cases it is recommended to include over-voltage (OVP) and transient protection on the power supply to the printer.

SE Code: 14.6:10 - Secondary 42V Power supply error
Description
The secondary 42V power supply provides the required 42 Volts power to the rear and front spindle
motors, to the scan axis motor and the drive roller motor. Therefore without this power the printer is not
able to function.
The actual detection is done in the Main Interconnect Board by capturing the bypass signal sent to the
Printmech Board. The voltage is measured and if below a threshold the error is triggered.
The 42v secondary power supply is powered by the single AC power phase.
Problem causes in order of importance
A. False failure
B. Lack AC Single phase power in 42 secondary power supply/Main Interconnect detection/42v
power path to Main Interconnect.
C. Power link in 42V secondary power supply (Check safety rely link)
D. Short circuit in any of the 42V supplied areas
E. Actual 42V secondary power supply failure
Corrective action
Troubleshooting
False failure
1. Turn OFF the printer, wait 10 seconds, and switch On and restart the printer.
Lack AC Power in 42 secondary power supply
2. Check the Power supply 42V with a multimeter directly in the secondary power supply terminals.
If it is giving 42V, check arrival of power in cables connected to J22/J23 on the Main Interconnect
Board.
• If 42v power arrives, to the Main Interconnect, replace the Main Interconnect Board page
520.
• If power does not arrive, check the power path 42v secondary PSU -> Main Interconnect,
repair or replace cables or connections as appropriate.
If it is not giving 42v, check the single phase power arrival to Secondary power supply. If it does
not arrive, check the single phase power path to 42v secondary power supply and repair as
appropriate. Ensure correct connections for the 42v PSU and that the short-circuited signal arrives
from the safety relay when active
Power link in 42V secondary power supply (Check safety rely link)
3. Check power link from safety rely to secondary 42V power supply (small black connector at the rear
of the PSU) if failed repair. In order to work the link needs to be short-circuited the safety relay.
The power link enables the secondary 42v power supply, once the safety relay is closed, and the
line is short-circuited.
Short circuit in any of the 42V supplied areas
4. Check for possible short-circuits in any of the feed areas. Disconnect all connections from 42V power
