Dissecting the New Laser Jet Event Logs

I will  be discussing only the paper path  jam events or errors dealing with the Base Unit  M602 Printer’s Paper Path.  The sensors and their locations haven’t changed,  just the the way the they are read from the event log.  The fuser delivery sensor name has changed for the 4250 as you will see.  I reference the old errors  and note similarities which helps me and I hope you to understand their meaning.

How to Read the New Event Codes
What do all these numbers and letters Mean?

There are three sets of two digits that all have a Designation.
〈〈.〈〈.〈〈

The first set of two digit codes
“13” = Generic Jam.

The second set of two digits codes are Sensor Locations.
A2 = Pre-feed sensor (PS102)
B2 = Top-of-page sensor (PS103)
B9 = Fuser delivery sensor (PS700)

The third set of two digit codes are …
The first digit is whether it was Late to the sensor or if it stopped at the Sensor.
A = Stopped
D = Late
The second digit is the source tray,
Tray 1, 2, 3, 4

Error Codes

60.X errors in HP LaserJet 4250 Series Printer

A 60 .X error means that the machine is experiencing a problem with the paper tray lift motor.  Here is the description and the recommended action HP gives for the 60.X error.

60.2 printer error
The tray 2 lifter-motor is not functioning.
1 Turn the printer off and then on.
2 If the error persists, turn the printer off.
3 Verify that the tray 2 lifter wire-harness is full seated in its connector on the dc controller PCA (location J93).
4 Replace the tray 2 lifter-driver assembly. See Tray 2 lifter-drive assembly.
5 Replace the dc controller PCA. See Dc controller PCA.

Notice that the error 60.X in where X=The specific tray having the problem.
60.2 = tray 2
60.3 = tray 3
60.4 = tray 4

In my experience I have never replaced a dc controller or a tray lift motor for this error code.  I’m sure that there have been cases of this but doesn’t happen very often.  The more popular issue has been a broken paper tray.

Tray Length Guide-RM1-1088
Paper Tray Length Guide

The rear length guide will break and that causes the lift mechanism on the tray to bind and stop the lift motor and it will throw the code.

Next, if that isn’t the problem you will need to look at the tray lift  motor tension spring.  These break and will cause the 60.X errors also. see illustration

Tray Lift Motor and Tension Spring
Lift Motor/Tension Spring

It’s always nice to have an extra spring in your goody box, but we all know that’s would be to good to actually happen.  Most of the time I can find the broken spring inside the machine or the customer found it and saved it.  Just reform the spring and viola your back in business!

That’s it!  This isn’t too difficult of a problem to fix you just have to know where to look.  I will have a repair video for this very soon.  Keep and eye out for it.

 

 

Error Codes, printers

WTF Does “Misprint” Mean?

What is a “misprint”?    It’s another term Hewlett Packard has come up with to describe a paper jam in their laser printers.  The new error code associated with it is 13.0000.   The earlier version of this would be 13.01 .  The confusion comes from people not knowing what a misprint is.  We are  so used to using the term “paper jam” or “mis-feed”  that we believe it has to be a serious problem and we ” overplay this “misprint” thing… help!

Here are the definitions for the term misprint.

mis·print

Misprint Press [OK]
Description
Paper has been delayed as it moves through the product.
Recommended action
Press the OK button to clear the message.
To avoid this problem, try the following solutions:
1. Adjust the paper guides in the tray. Make sure the front paper guide is pushing the paper against the back edge of the tray.
2. Use paper that meets HP specifications. Store paper unopened in its original packaging.
3. Use the product in an area that meets the environmental specifications for this product.

In the newer color laser printers “Misprint” is used to differentiate between a regular paper jam and a paper jam that is not sent within the correct timing of the machine.  Here’s what happens step by step in a color printer with misprint problems.

At the beginning of a print job the information is sent from the computer to the printer.  The image has already been created on the ITB (Intermediate Transfer Belt) ahead of time . The full image is laid onto the ITB with each color of toner used in the document.  The paper did not feed correctly and  in this situation the paper never makes it to the registration sensor.  Everything in a printer is precisely timed, so the toner is about to be wasted and sent to the waste toner bin.  Now, because that image is unusable the machine begins to clean the ITB which is the “Cleaning Mode”. Then after all this is over the machine will give the message of  “Misprint”.This terminology is not limited to just color machines it also is used in Black and white or monochrome printers.  Again, the description is the same “Paper has been delayed as it moves through the product”.  So there you go, “Misprint” just means that you have a paper jam, so you can relax and remove your paper jam without any stress at all.

HP Color LaserJet 4700 Series Error Codes

For Models 4700, 4700n, 4700dn, 4700dtn, 4700ph+

Control panel messages
Control panel messages are divided into three types, depending on their severity.
Status messages
Warning messages
Error messages
Within the error message category, some messages are ranked as Critical error messages. This section explains the differences between the control panel message types.
Warning messages
Warning messages inform you of data and print errors. These messages typically alternate with the Ready or Status messages and remain displayed until the button is pressed. If CLEARABLE WARNINGS is set to JOB in the printer’s configuration menu, these messages are cleared by the next print job.
Error messages
Error messages communicate that some action must be performed, such as adding paper or clearing a paper jam. Some error messages are auto-continuable; if AUTO CONTINUE=ON the printer will continue normal operation after displaying an auto-continuable error message for 10 seconds.

NOTE Any button pressed during the 10-second display of an auto-continuable error message will override the auto-continue feature and the function of the button pressed will take precedence. For example, pressing the Menu button will display the main menu.
Critical error messages
Critical error messages inform you of a device failure. Some of these messages can be cleared by turning the printer off and then on. These messages are not affected by the AUTO CONTINUE setting. If a critical error persists, service is required.  The following table lists and describes control panel messages, in alphabetical order.

With certain messages, the job might  not finish printing or the print quality might be affected. If the message is related to printing and the auto continue  feature is on, the product will try to resume printing after the message has appeared for 10  seconds without acknowledgment.

For some messages, restarting the product might fix the problem. If a critical error persists, the product  might require service.
