20 Most Recent HP Laserjet CM2320nf All-In-One Color Printer Questions & Answers

HERE'S THE SOLUTION THAT WORKED FOR ME: I have been working HP LaserJet printers for many years. I have not ever seen this problem before today. In my case I was working on a HP LaserJet M605. After booting up, it always claimed that the cartridge shipping lock had not been removed, but it had been removed.The cartridge was good, the formatter was good, and the DC controller was good. Upon taking a close look inside the cartridge bay, I noticed that one of the two spring-wire electrical contacts located under the bottom left side of the toner cartridge was not at the correct angle. There are two inverted V- shaped wire contact springs that protrude out of slots in the black plastic frame which supports the registration and transfer assemblies. These two springs connect points on the toner cartridge to the engine power supply board. One of them was pointing to 12 O'clock instead of 1 O'clock which led me to suspect that it wasn't making contact on both ends. In order to access the springs, the entire metal left-side frame has to be removed. With the side plate removed I could see that the springs have two spots with coils which snake around pegs. One of the springs had come off both of the pegs and no electrical connection to the vertical copper contact post on the power supply board was being made. I put the dislodged spring back in place with needle pliers, and in order to keep it from coming off again, I drilled out the upper plastic peg and installed a washer-head screw into the just enlarged hole in the center of the plastic peg to keep the spring held down at the upper coiled part and thereby keeping the whole spring from being knocked out of place again. This job took about 2 hours because there are a lot plastic cover and paper tray guide parts, two fans, and many screws that need to be removed to take off the left-side frame to reach the location of the problem spring.

if you don't find nothing inside printer and you are SURE there is no paper inside machine try to clean or replace pickup roller, if you wanna be sure about that try to print from Try1, if it work the problem is in try 2

A decent printer should print a #10 envelope without a problem. If this model won't do so, return it and get another printer. Suggest Epson or Canon -- AVOID HP printers.

Just take out your toner cartridge. If you find an orange color notch on the left side, just remove it. Re-insert the cartridge and restart the printer . This should resolve your issue.

replace the cartridge

When you press the COLOR copy button on printer, and it does copy in COLOR, then it is probable that the printing driver has been modified to print in greyscale. When was the last time it printed in color? Was there a Windows Update for the printer done recently?

The product has experienced a developer motor error Turn off the power and wait 30 seconds or so and power back on. if the unit still errors you have a bad developer motor or the DC Controller (board that drives the motor) is bad. the unit might not be wort the cost of repair but I have included the part numbers. motor: RL1-1800-000CN DC Controller:RM1-5431-000CN

Bad problem , check if there is some piece of paper ... otherwise yuo need a thecnic , may be is a paper sensor damaged .

No. Color printer need ALL cartridges with ink to print.

Prior to providing a final answer, one question...does it do the same thing whether you scan through either the document feeder OR the flatbed? Both options use the same scanner, BUT they view the scan through different viewpoints. The document scanner uses additional mirrors to get the image, and these mirrors tend to get dirty. The flatbed views the image directly through the glass. If it does the same thing through both flatbed or feeder, then a scanner firmware update might be in order?

Not a good situation, since this usually means the scanner assembly is having issues and doesn't park itself properly, causing the initialization problems. This happened to the one I had and was going to cost too much for parts to fix, so I now have a new all-in-one. I usually can fix these little issues, but this one left me scratching my head. Sorry that this is not actually a solution, but bad news ;(

Per my service manual for this printer, the 59.C0 error states: The product has experienced a developer motor error. Recommended action: 1. Turn off the power by using the power switch, and then wait at least 30 seconds. 2. Turn on the power and wait for the product to initialize. If the error persists, replace the developer motor. If the error persists, replace the DC controller
