The printer driver has not been installed properly.
→ Follow these steps to check and see if the printer driver 

is installed.

1 Click the "Start" button, click "Control Panel", and 

then click "Printer".
In Windows 7, click the "Start" button and click 
"Devices and printers".
In Windows XP, click the "start" button, and then 
click "Printer and Faxes".
In Windows 2000, click the "Start" button, select 
"Settings" and then click "Printers".

2 If the "SHARP MX-xxxx" printer driver icon is 

shown but you still cannot print, the printer driver 
may not have been installed correctly. In this case, 
delete the software and then reinstall it.

The tray size settings are not the same on the machine 
and in the printer driver.
→ Make sure that the same tray paper size is set on the 

machine and in the printer driver. To change the tray's 
paper size setting on the machine, see "LOADING THE 
PAPER TRAY" or see "CONFIGURING THE PRINTER

The specified size of paper has not been loaded.
→ Load the specified size of paper in the paper tray.

A print job containing more data than can be held in 
the print memory is sent to the machine.
→ Disable the ROPM function on the "Configuration" tab 

of the printer driver setup screen. If you need to use the 
ROPM function, divide the pages of the print data into 
two or more print jobs.

→ The memory allocated to the printer function can be 

changed in the user program "Memory for printer".

Simultaneous use of two or more application software 
programs.
→ Start printing after quitting all unused application 

software programs.

–

The paper is loaded so that printing takes place on the 
rear side of the paper.
→ Some paper types have a front and rear side. If the 

paper is loaded so that printing takes place on the rear 
side, toner will not adhere well to the paper and a good 
image will not be obtained.

You are using paper that is outside the specified size 
and weight range.
→ Use copy paper within the specified range.

Paper curled or damp.
→ Do not use curled or crimped paper. Replace with dry 

copy paper. During periods when the machine is not 
used for a long time, remove the paper from the tray 
and store it in a dark place in a bag to prevent moisture 
absorption.

–

You did not set sufficient margins in the paper settings 
of your application.
→ The top and bottom of the paper may be dirty if the 

margins are set outside of the specified print quality 
area.

→ Set the margins in the software application within the 

specified print quality area.

–

The paper loaded in the tray is not the same size as 
that specified in the printer driver.
→ Check if the "Paper Size" options suit the size of the 

paper loaded in the tray.

→ If the "Fit To Paper Size" setting is activated, make sure 

that the paper size selected from the drop-down list is 
the same as the size of the loaded paper.

–

your requirements.

–

Paper is not loaded properly.
→ Make sure the paper is properly loaded.

You did not correctly specify the margins for the 
application in use.
→ Check the layout of the document margins and the 

paper size settings for the application you are using. 
Also check if the print settings are specified correctly to 
suit the paper size.

–

The setting for the print density is not appropriate.

You have not specified a suitable value for the "B/W 
Threshold" setting.
→ If you are scanning with a TWAIN-compliant 

application, make sure that a suitable value is specified 
for the "B/W Threshold" setting. A larger threshold 
value makes your output darker, while a small 
threshold value makes it lighter. To adjust the threshold 
automatically, click the "Auto Threshold" button on the 
"Image" tab of the "Professional" screen.

You have not specified all scanning preferences 
appropriately.
→ Scanning a large area at high resolution results in a 

large amount of data and extended scanning times. 
The scanning preferences should be set appropriately 
for type of original to be scanned, i.e., Text, Text/
Graphics, Photograph.
