For fusers, HP used to only send you one or two general error codes. They’re being more precise in-depth now, making it easier to troubleshoot errors like the HP laserjet cm3530 50.8 fuser Error and potentially fixing the problem without buying unnecessary pieces. Surge arrest or power strips are one thing that has been known to trigger issues with fusers. Every day, more and more electrical devices are used in workplaces. Power strips are used to ensure that anything can be plugged in and used. LaserJets are similar to large heaters in that they consume a lot of electricity, so they must be plugged into their own socket with no other heating devices nearby.

Troubleshooting the HP laserjet cm3530 50.8 fuser Error

1. Verify the fuser is installed correctly and fully seated.50.8 <em>fuser error</em> - HP Color Laserjet 3000, 3600, 3800, and CP3505 photo

2. Check that connector J6007 on the fuser is seated correctly. Replace the connector as necessary.

3. Turn off the printer.

4. Remove the fuser.

5. If there is no conduction in the sub thermistor, measure the resistance between fuser connectors J6007LA-1 and J6007LA-3. If the resistance is not 100 ohms to 3 Mohms, replace the fuser.

6. If there is no conduction in the fuser heater, measure the resistance between fuser connectors J6007LAF-1 and J6007-2. If the resistance is not 5 ohms to 1 ohms (100 to 127 V) or 20 ohms to 1 ohms (220 to 240 V), replace the fuser

7. Upgrade the DC controller firmware.

8. Replace the DC controller PCA.

Method 2-

1. Turn the machine off then back on. Sudden interruptions in power can cause errors like this. Thunderstorms, winding days, utility work nearby are causes for possible sudden and quick power outages that can lead to incorrect fuser temperature readings.

2. Check the power source. For testing purposes make sure that you have the machine plugged straight into a wall outlet.

3. If you just replaced the fuser make sure that it is the right voltage for the machine.

4. Replace the fusing assembly.
