Toner low or defected drum

Okay, you are not going to like this but using the rebuild kit is the failure.

Go get a factory new cartridge and see what happens.

Hi
I recently had this problem - tested fuser and all sensors.
The fix is to reset the memory.
To do this, enter the Maintenance mode. Menu, * 2864
(enter the number quickly)
then type 01 ( zero one ), this will reset all memory including the user settings.
Finally type 99 to exit Maintenance mode.
The printer will restart and the error will be gone. Test out with copy and printer reports
Hoping this fixes your problem
Regards

Hi. I provided you a link for the user's manual of the printer. Please click here.

No they are not. The drum unit (DR510) is a separate cartridge from the TN570 toner cartridge. The toner will last around 6,000 pages while the drum unit is good for 20,000.
Good Luck and Thank You for using Fixya.

It is part of the Network User's Guide (section 10) and the Software User's Guide (section 3 for a PC using Windows, Section 8 for network scanning), not the User's Guide. The directions below are for XP and Win2K primarily. Slight changes may exist with other OS versions. (Full software is not available for Win7 so the buttons on the unit will not work. You will need to launch scans from the computer only. You can use Windows Paint or Fax and Scan without needing third party software. Then attach the file to an email either in the email software or by right clicking on the file and choosing Send to Mail Recipient.)

For either use, put the document face down on the glass or face up in the ADF.

If you use a directly connected computer, you need to set the destination for the Scan to E-mail in the Control Center (section 4-4 in the Software User's Guide). Open this program and make sure the correct machine is in the drop-down menu. This program needs to be running to hear the buttons being pressed. Click on E-mail to set which program will get the scanned document as an attachment for your e-mail. You can also set the resolution and type of attachment. If you do not want to use available file formats, you will need to scan in PaperPort (or other software) and then use that to attach the file to the e-mail. Then click Scan to launch the scan from the unit. Hit Set when ready to send.

If you have the unit set up on the network, then you can enter the LAN setup in the Front Panel (or a browser). Hit Menu 6 (and then the appropriate number for the next feature), such as TCP/IP, DHCP or Static IP (these are under 1), SMTP, POP3, Mail Address (Menu 6 2). Setup the Scan to email with Menu 6 7 1 for color and Menu 6 7 2 for black and white.

This automatically sends the item to the email server or PDF as either a PDF or JPEG. Then you need register the PC that will get the file to the unit, if you use scan to email (PC). (Your version of Windows will matter for exactly where the information is: Control Panel > Scanners and Cameras or Control Panel > Printers and Other Hardware > Scanners and Cameras.) Right click on the icon for the unit and select Properties to see the Network Properties box. Go through all of this set up including the Scan To Button. Then the Control Center will launch the e-mail program when it "hears" you press Scan, select Scan to Email, press Set, then choose PC and press Set again. (or select the destination PC which has e-mail access and press Set again). Scanning will start.

If you have set the POP3 and SMTP servers and the unit can directly access them, then you can scan to e-mail and enter the recipient address. Press Scan, select Scan to Email, press Set, choose Email Server and Press Set again. Adjust the scan quality as desired pressing Set at each step. Once you go through all of the layers, the LCD screen will prompt you for the recipient's email address. Then press Start.

I hope this helps.

mcdevito75 here, Best Bet, see your local Staples, Best Buy, etc. for a new cd.

Move the blue slider on top of the drum unit 10 times back and forth.

Replace the drum cartridge.

it depends on the damage itself...there is a possibility that after you open it and use a hair drier with normal air..not hot..and dry it well to work again ...The water just temporary change the contacts cause it is a good electric conductor ...and thats why it not work ...so first try to see if it works after you evaporate all water from all over ...but do not open it until you are sure that its dry..
and if it do not works ...try to see if you find a board fro it ..and if it is worth ..cause sometimes it cost more to repair than to buy a second hand one that will end up better than the one repaired and work just fine ..
take in price the hand work if you do not do it yourself..
in case you are handy and think you can manage to change it ..than it is worth repair it ..

whatever system you're using, check the envelope settings information in the program your using, this might solve your answer. or, go to the printer setup page and check to see if you have options for printing envelopes. hope this helps.
