Page 16: Choosing A Place For The Printer
Choosing a Place for the Printer When selecting a place to set up your printer, be sure to follow the guidelines below. Place the printer on a flat, stable surface. Place the printer close enough to the computer for the printer’s interface cable to reach it.
Page 17 If you plan to use a printer stand, follow these guidelines: Use a stand that supports at least 16.0 kg (35.3 lbs) for the LQ-570 or 22.0 kg (48.5 lbs) for the LQ-1070. Never use a stand that tilts the printer at an angle of more than 15 degrees from horizontal.
Page 18: Assembling The Printer
Removing the protective materials During shipping, packing materials protect the printer and a locking clip protects the paper-tension unit. Before you turn on the printer, you must remove the locking clip as described here: Remove the paper guide. Lift the printer cover up and off.

Page 24 2. While holding down the LF/FF (Line Feed/Form Feed) button, turn on the printer. The printer beeps and the platen turns for a few seconds, signalling that the printer is in self-test mode. 3. Move the left edge guide until it locks in place next to the guide mark.
Page 25 Testing the Printer CAUTION: Run the self test using paper at least 210 mm (8.2 inches) wide for the LQ-570 or 360 mm (14 inches) wide for the LQ-1070; otherwise, the print head prints directly on the platen. Insert a sheet of paper between the edge guides until it meets resistance.
Page 26: Connecting The Printer To Your Computer
Connecting the Printer to Your Computer If the self test prints correctly, you are ready to connect your printer to the computer.

Page 50: Printing On Special Paper
Printing on Special Paper In addition to printing on single sheets and continuous paper, your printer can print on a wide variety of other paper types, such as envelopes, labels, and multi-part forms. Before printing on special types of paper, you need to change the paper-thickness setting.
Page 51: Multi-Part Forms
Note: Print speed is reduced for paper-thickness lever settings of 2 and above. Multi-part forms Your printer can print on both single-sheet and continuous multi- part forms. You can load single-sheet multi-part forms only in the front paper slot. You can use multi-part forms of up to four parts (including the original).
Page 52: Labels
Since labels are especially sensitive to temperature and humidity, use them only under normal operating conditions. Do not leave labels loaded in the printer between jobs; they curl around the platen and may jam when you resume printing. To remove labels from the paper path after you finish printing, first tear off the labels at a point before the paper slot.
Page 53: Envelopes
Always set the paper-thickness lever to position 2, 3, or 4 depending on the thickness of the envelope. Always feed envelopes by inserting the wide edge into the printer. CAUTION: Only use envelopes under normal operating conditions. Printing on the edge of an envelope can damage the print head.

Page 66: Micro Feed
When you adjust the loading position of single-sheet paper, the printer remembers the new position until you turn off the power. The loading position returns to the factory setting when the power is turned on again.
Page 67: Adjusting The Loading Position
Adjusting the loading position The loading position is the position of the paper after it has been automatically loaded by the printer. If printing is too high or low on the page, change the loading position with the micro-feed feature as follows: 1.
Page 68 For continuous paper, the printer remembers this new position even after it has been turned off and back on. The printer has a minimum and maximum loading position. If you try to advance the loading position beyond these limits, the printer beeps and the paper stops moving.
Page 69: Tear Off
After you have finished printing, you can use the tear-off feature to advance continuous paper on the push tractor to the tear-off edge of the printer. You can then easily tear off printed sheets. W h e n you resume printing, the printer automatically feeds paper back to the loading position.
