Example #1: If you are having a telephone conversation and a fax communication signal comes through on your Call Waiting Caller ID feature, you can verify that the second call is a fax by switching to it. You have the option to receive the fax call, by asking the first caller to hang up to clear the line. Example #2: If you are sending or receiving a fax message while a Call Waiting Caller ID (or other custom feature) signal comes through on the line, the signal can temporarily interrupt or disrupt the fax data. BrotherÕs ECM feature should help overcome this problem. This condition is related to the telephone system industry, and is common to all devices that send and receive information on a single, shared line with custom features. If avoiding a slight interruption is crucial to your business, a separate line with no custom features is recommended.

205TROUBLESHOOTING AND MAINTENANCE DIFFICULTY SUGGESTIONS Printed pages are marked Markings may disappear by themselves. Try copying at regular intervals multiple pages to clear this problem. Markings may occur if the MFC has not been used for a long time. A possible cause is that the surface of the drum is scratched. You must then replace the drum unit with a new one. If the markings do not disappear, it may be that the drum was marked or damaged by excessive exposure to light. In this case, replace the drum unit with a new one. Printed pages are blurred at Certain environmental conditions such as humidity, high the center or at either edge temperatures, etc. may cause this condition to occur. Make sure the MFC is placed on a flat, horizontal surface. Remove the drum unit with the toner cartridge installed. Try rocking them from side to side.

206CHAPTER NINETEEN Difficulties Setting up the Software Problem Using the HP Pavilion PC and the ÒHP DEMOÓ Screen Saver If you select the ÒHP DemoÓ screen saver on your HP Pavilion PC after you have installed the Multi-Function Link Pro software, the System.ini file is overwritten and you cannot use the Brother MFC to print, scan, or for Remote Setup. If you have used the HP Demo screen saver already, you must edit the System.ini file as follows: [boot] ;comm.drv=comm115.drv comm.drv=brmfcomm.drv [386Enh] DEVICE=C:\WINDOWS\SYSTEM\Bi-Di.386 If you do not want to edit the System.ini file, please change the screen saver to another one and Re-install Multi-Function Link Pro again. Bi-Directional Parallel Ports (nibble and byte modes) The MFC supports both nibble (AT) and byte (Bi-directional) mode parallel ports. If your PC supports byte mode, scanning and fax reception will be at a faster speed. To verify or change the parallel port mode, please check your system BIOS in the CMOS Setup or contact your computer manufacturer for assistance. Some older PC models support only nibble mode. Generally, newer models support both nibble and byte modes.
