MT151 Printer Will Only Print Half The Width Of The Page

No Display when Powered On

This can be caused by several things:-

• Check that your interface card is correctly inserted and locked into the rear of the printer. The lock lever to the right of the interface slot should be in a vertical position when locked.

• If it is a brand new printer or brand new interface check that the correct interface has been inserted. E.g. if the printer is a MT150/9 and the interface inserted is for a MT15X/24 and vice versa. See the above note about Interface Exchangeability

• This can also happen if an old MT13X interface has been inserted. The interfaces for the MT13X and MT15X look similar and will physically fit but because the MT13X had no display it gives a blank display on the MT15X.

• If all the above are correct it could be a genuine fault on the printer or interface and you should contact our Repair Centre for advice on getting the printer repaired.

Setting The Top of Form, Form Length and Tear Position

Follow these instructions in the order given:

• SETTING THE FORM LENGTH - Measure the length of your stationery in inches. Take the printer off-line, press the set-up key, press the button under the display under the option Menu. Then press next until Papopt and Formlen is displayed, press Formlen it gives the option of Lines or Standard. If you select Lines use the up or down arrows in the display to set the form length of your paper in lines i.e. 6 lines - 1 inch (6 lines per inch is the default value in the menu of the printer, however this can be changed) so 66 lines = an 11 inch form length. When you have the desired setting press Set an asterisk should appear next to your selection. Exit the menu by pressing the set-up key. If you choose to select Standard instead of Lines it allows you to set various pre-programmed paper sizes i.e. A4 etc.

• SETTING THE TOP OF FORM POSITION - Unload the paper and place it in the first three pins of the tractor. Press TOF in the menu and paper will then load automatically. This display reads FORMADJ = 12/72. This setting gives a print one line down from the top of the page. If you require a smaller top of form press arrow up or down to 0/72. For a 1-inch top of form set FORMADJ - 72/72. When you have the desired setting press Set and an asterisk should appear next to your selection. The adjustment will be the amount of gap between the top edge of the paper and the front tear bar. When Set is pressed the printer will return the paper down to the print-head top of form position ready for printing.

• SETTING TEAR OFF POSITION - After setting top of form the menu will go to off-line with a tear option in the display. Press tear and the paper will advance to the tear position. This can then be adjusted with the up and down arrow keys. To set press tear again.

NOTE - If the above procedure does not work power on the printer holding down all four buttons under the printer's LCD display this will restore the factory default values. Then follow steps 1 to 3 again. Please note all the printer menu settings will have to be set-up from scratch so any settings that you have made will change back to default.

If it were a genuine hot printhead it will come up after the printer has been printing for a time. If the printer comes up with this message straight out of the box or after a new interface has been purchased then please check that the interface inserted is the correct one for the printer you have. This error has been known to come up if the wrong interface has been inserted. E.g. if the printer is a MT150/9 and the interface inserted is for a MT15X/24 and vice versa.

See the following note about Interface Interchangeability.

The 9 and 24 needle interfaces do differ from each other. The 9 and 24 needle interfaces are specific to that type of printer and not interchangeable. The correct part numbers are:

• MT150/151-9
• Parallel Interface = 047021
• Serial Interface = 047050
• MT150/151-24
• Parallel Interface = 047022
• Serial Interface = 047051

If you have been supplied the incorrect part for your printer please refer back to your supplier.
