Phaser 6121MFP Service Manual 4-19General TroubleshootingOne Page Fax Printed on Multiple PagesA single page fax will print on multiple pages if the original document paper size istoo big.You can use the Scale to Fit function to select whether documents longer than thecurrent paper size are printed reduced, split, or discarded. In the Fax menu, selectFax Default Setup > Receive Option > Scale to Fit and then select one of thefollowing options.On: The document is printed at a reduced size.Off: The document is printed at full size and split onto multiple pagesCrop: The document is printed, but any part that does not fit within the page iserased.Other Fax ProblemsBranch Connection (Parallel Connection)During Fax reception, if the handset of another telephone on a branch connectionis lifted, the received image can be corrupted or a transmission error may occur.Branch connection may also interfere with Caller ID, Call Waiting, or the receivingoperation of the connected telephones.Call WaitingIf a call comes in during Fax sending/reception, the image may be corrupted.Digital Subscriber LineDigital Subscriber Line (DSL) is a high-speed digital transmission method usingexisting telephone lines. Because the line is used for both voice and datatransmission, various problems may occur, such as noise during spokenconversation, low sound volume, and mis-dialing. Replacing the splitter mayimprove the situation.The Digital Subscriber Line cannot be directly connected to a fax machine; the linemust be connected via a filter.There are several types of DSL:• ADSL (Asymmetric Digital Subscriber Line) – Transmits digital information at ahigh-speed bandwidth on phone lines. ADSL provides continuously availableconnection with differing upstream and downstream transmission speeds andsimultaneously accommodates analog (voice) and digital information on thesame line. Downstream data rates are offered from 512 Kbps to about6 Mbps.• SDSL (Symmetric Digital Subscriber Line) – Runs over one pair of copper wireswith symmetrical upstream and downstream transmission speeds up to3 Mbps, with a maximum range up to 3 km.• VDSL (Very high Bit Rate Digital Subscriber Line) – An xDSL technology thatprovides faster data transmission over a single twisted pair of copper wires.VDSL transmits data from 13 Mbps ~ 55 Mbps over short distances, usuallybetween 1000 and 4500 feet.
