Troubleshooting Processor Error Codes
IMPORTANT: When doing the procedures in this document, you must use safe work
practices and wear the correct Personal Protective Equipment (for example, Safety
Eyewear) according to your Company's Standard Operating Procedures.
Instructional
This bulletin provides information on how to troubleshoot Processor Error Codes on the
DRYVIEW 5700/5950/6950. Always make sure you have the latest software loaded.
The Processor uses the following components:
 Drum(s)
 Machine Control Board (MCS)
 Harness
 Power Supply

Drum
The Drum has:
 Heaters (Lamp or Blanket):
 Lamp Heaters are on the DV5700, DV5950, and DV6950 (Outlet).
 Blanket Heater is only on the DV6950 (Inlet).
 Resistance Temperature Device (RTD) that provides electronic feedback to the
MCS board to control the temperature of the Drums
 Internal Thermal Switch that opens when it reaches 168 °C
 For the Lamp Heater, the Thermal Switch can automatically reset itself
 For the Blanket Heater, the Thermal Switch must be manually reset.
MCS
MCS board controls the temperature of the drum(s). Based on the feedback from the
RTD on the Drum, the MCS board will gate a Triac(s) that will provide voltage to the
Drum that will cause the Drum Heater to increase the temperature.
Definition of Processor Error Codes
28-501: Processor RTD Short Circuit. This error occurs when the temperature calculated
by the MCS from the voltage measured by the RTD is almost zero.
28-509: Processor did not complete Warm-Up. This error occurs when the MCS checks
temperature near the end of the warm-up cycle.
28-510: Processor RTD Open Circuit. MCS detected a sudden change to infinite
resistance in the RTD circuitry. This error usually occurs with an overheat error.
28-551: Processor Heater Failure. Very similar to 28-509 but the MCS looks to see if the
temperature is increasing at the expected rate.
28-554: Over Temperature Error. This error occurs if the MCS detects the temperature is
148 °C or higher.
Logs
If you have not been using the Application Log for Troubleshooting, it is time you
started. The Application Log can help in determining what caused the error to show.
For Processor Errors, it is very valuable.
Here are some examples:
We used Advanced Filtering of the logs to remove a lot of information that did not help.
We also manually removed some of the information that would show up in the cells to
make it fit this bulletin (see next page).

Processor::failProcessor(): called.
Partial Log (A) above will always show in the Application Log. Note that the time
(17:32:01) is the same for each entry. That is because it captures all of that data at the
same time. You can see that after PSB_WARMUP and PSB_HEAT_ENABLED there is
a 1. A 1 is considered an active state. So, in this case, the machine is warming and the
heaters are energized. A closer look will show that PSB_M_ZONE_SSR_FAIL_ERR
also has a 1. This is not a normal state but indicates that there has been a failure. This can
be confirmed by the last line that states failProcessor():called.
A couple things about PSB_M_ZONE_SSR_FAIL_ERR: the M means Motor Zone and
because it had the 1 after it, we know that the Motor Zone has an issue. Motor Zone is
part of the Blanket Heater (Inlet) Drum, so this means that we have issues with the Inlet
Drum. This does not mean that there may not be other issues with the other zones in the
Blanket Heater Drum. The machine pretty much stops at the first error it sees.
If the DV6950 Lamp Heater Drum had issues, you would see a 1 on the PSB_Q_ZONE.
Because the DV5700/5950 only use one drum, the description in the log will be different.
Now let’s relate the log information to the error codes. For simplification, we will only
look at one of the zones.

Partial Log (A), captured above, says that the machine has a 28-551 error. Of course, the
machine told us that via the Local Panel. But, now we know it is a problem with the Inlet
drum.
So, what caused the error? Below is another log capture from the same machine. This
time, we used the Advanced selection and selected Text; Text; Contains; Duty: to isolate
to only the lines that have the word Duty: in them. The line for Printer was manually
added to show the countdown.

You should notice a few things right away in the Partial Log (B). The temperatures of the
Non Motor Zone, the Center Zone, and the Motor Zone have not changed much, but the
temperature of the Quartz Zone is showing an increase. The Duty is always at 100
(calling for heat). That confirms what we learned earlier that the Quartz Zone does not
have an issue. Because all of the Blanket Heater Drum Zones have problems, it looks like
the Thermal Switch has opened. Later, you will learn how to check this.

The Normal Sequence Log above was shortened on the front end to reduce the size. The
machine is calling for heat (Duty: 100) and you can see the temperature is increasing.
When the machine reaches near 130 °C, the Duty will start to change and will move the
temperature to the operating temperature of 124 °C.

On the Failure on DV5950 log, the machine never reached the 130 °C and started
lowering the temperature. Duty remains at 100. Suspect the Thermal Switch or the Lamp
Heater element opened.
Troubleshooting Processor Error Codes
This section focuses on troubleshooting the MCS and the Drum. This does not mean that
the harness or Power Supply should be eliminated from causing Processor errors. So far,
we have not seen issues with the harness or power supply.
Machine Control Board
DV5700/DV5950 (SP9G0249/SPAA0248)
MCS boards are not the same for the DV5700 and DV5950, but the location of certain
components are the same.
If the machine declared a 28-551, 28-554, or 28-509, check the 4 resistors (R119, R120,
R136, and R137) for damage (see R136 and R137 in the picture). If damaged, replace the
MCS board.
In 2014, there was a change made to the DV5700, DV5950, and the DV6950 MCS
Boards.
DV5700
SP9G0249
Revision N to P
DV5950
SPAA0248 Revision G to H
DV6950
SPAA9653 Revision C to D
Note: The revision level of these boards may be higher now and already have this fix.
Page 6
Carestream Health, Confidential
Pub No. SB9K1387
This change dealt with the RTD circuits and the effects of Electrostatic Discharge (ESD).
ESD effected how the temperature is measured by the RTD circuitry. The ESD would
cause R208 on the DV5700/5950 to be out of specification. Because of the 4 Zones (1 for
the Outlet Drum and 3 for the Inlet Drum) on the DV6950, R208, R343, and R129 for the
Blanket Heater and R398 for the Lamp Heater (see DV6950 picture below) could become
out of specification.
Note: Always unplug the connector(s) for the drum when reading resistances on the MCS
board or the Drum. This will prevent reading resistance from other circuits.
If the MCS board revision level is below P (5700), H (5950), or D (6950), check the
appropriate resistor(s) for 1K ohms +/- 0.1% (see resistor(s) location below). If the
resistor is out of tolerance, replace the MCS board.

Lamp Heater Drums (DV5700/5950/6950)
5700/5950 have the same Lamp Drum with the same part numbers:
SP9G6746 Assembly: Drum - processor; 120 V; RoHS compliant
SP9G6748 Assembly: Drum - processor; 240 V; RoHS compliant
6950 has a different Lamp Drum due to a different power:
SPAB8122 Assembly: Drum—processor; 400 W, 120 V, lamp heater
SPAB8123 Assembly: Drum—processor; 400 W, 240 V, lamp heater
All Lamp Drums have the same schematic:

RTD resistance on pins 5 to 10 should read
approximately 1100 ohms at room
temperature. The resistance reading will vary
depending on how warm the drum is when
measured.
Heater/Thermal Switch resistance
on Pins 1 or 2 to pins 6 or 7 should
read from 2 – 12 ohms . Typical
failure is open.
Lamp Heater Drums have an automatic resetting thermal switch. If the thermal switch
opens, it will reset itself once the drum has cooled. Always allow the Lamp Heater Drum
to cool to room temperature before measuring the Lamp Heater/Thermal Switch circuit
resistance. If you read an open on the Heater circuit wires after the drum has cooled,
replace the drum.

For the Blanket Heater Drum, you will always read the resistance from pins 4 or 5 to pins
1, 2, or 3, on the five pin connector, depending on which Heater you are checking. The
Thermal Switch on a Blanket Heater Drum has a manually reset button. If the Thermal
Switch has opened, you will read an open circuit on all of the Heaters (HTR-1, HTR-2,
and HTR-3).
The RTDs should be read from pin 4 to pin 1, 2, or 3 on the 6 position connector,
depending on which RTD you are checking.

The Thermal switch is designed to open at about 168 °C. If this is the first time that the
Thermal Switch has opened, remove the four screws from the non Slip Ring side and
remove the end cap. Reach in and reset the Manual Reset Button by pressing in on the
white button.
If the Thermal Switch has been reset on a different call, then replace the Blanket Heater
Drum.
Summary
Once on site, check the MCS board for damage. Check the revision level of the MCS
board. If it is below the revisions listed earlier, check the appropriate resistor for the 1K
ohm +/- 0.1%. If it is within tolerance, check the drum. If it is out of tolerance, replace
the MCS board.
If the Thermal Switch has opened, reset it and let the machine warm up to operating
temperature. If the Thermal Switch opens again, replace the MCS board.
Any time you replace a Processor Drum you must calibrate the temperature of the drum
using a calibrated temperature meter. Refer to the Adjustments and Replacements
Section/Manual for the appropriate Laser Imager.
If you do replace the Processor Drum or MCS Board, make sure you complete the
returned parts form and list what you did to determine the part was faulty. For example, if
you measured the Heater/Thermal Switch resistance and found that the circuit was open
and the Thermal Switch had not opened, include that on the report. This information
provides important feedback in determining why the Processor Drum has failed.
