I have a two line TL86109. When I am on line 1, calls do not roll over on to line 2. How do I cause that to happen. I did not see that in the manual

Something has a shorted the line, unplug all phones, then call your line with a cell phone and see if it is still happening. If so, you will need to call repair. If not, plug 1 phone in at a time and call your number again, and repeat until you find the phone causing it to trip ring.. also if you do not have a inside wire maintenance agreement with you local phone company, start the test at the network interface device..

set your voice mail on phone

Is it on prints and copies? Or just prints or just copies.
There are 4 likely causes if the line is on both prints and copies. 1 The transfer belt has a scratch on it. 2, The Transfer belt cleaner, called the IBT cleaner is worn, or the fuser has a cut in one of the rolls. Also the 2nd BTR roll located on the left hand door may be damaged.
If the problem is only with copies, then the scanner glasses or mirrors are dirty.

The phone company controls the "HUnt".
If line 1 is busy and will not roll over to line 2, then it is the phone company....

Your roll over system is sending calls to the first line in the sequence and it does not differentiate between voice and fax. You will have to change the roll over so it does not send calls to your fax line. Your internal phone system may still use the fax line for outgoing faxes and voice calls but incoming fax calls have to be sent to the line the fax is on.

Call Encompass Parts 1-800-638-3328 or visit their website online. it could be your DMD board or check DMD Fan if it is not running replace it also remove any and all dust and Dirt if you see any and clean off optical lense make sure none of air ways are blocked with dust or dirt.

That is most likely the upper fusing roller with the line on it. I don't know if it is possible to just replace the roller. The source that I use only offers the complete unit (2 choices) one has a white connector, the other has a grey connector.

you will need to replace capisitor Cc10 its Value is 1000uf @ 16v the cap is a filter On Sw +9v Line , on pin 20 of Ic01, ( or corma Jungle IC)

You should have settings in your setup menu that allow you to center and adjust the height and width of the picture field which will allow you to move those lines (caused by a natural necessity of the receiver; synchronization) out of your view.

Not to discourage you, but here is an extensive thread from other Samsung owners with similar problems:

Sounds like the digital/DMD board has noise in those modes.
hope you are under warranty
