1 ). POWER REQUIREMENTS:

The Table below shows both the peak and average amperages with their associated duty cycles for a typical SP-327 printer performing various printing operations. The SP-327 operation requires large peak current pulses at low duty cycles. Therefore, the average power requirement is typically low.

NOTE on GRAPHICS MODE CURRENT: The average current required in graphics modeis verylow since it is limited by the data transfer rate. The Graphics Command requires the transmission ofat least 5 characters to print 8 dots on a line. A baud rate set at 9600 (approx. 1 msec / char transmission time) produces a 0.1 amp peak or a 10 mAmp average at a 12% duty cycle. The Graphics Command requires a minimum of 60 characters to print all 448 dots on a line. In this situation, a 6 amp peak or 140 mAmp average is produced at a 2.3% dutycycle.

7). ECHO BACK PRINTER MODE STATUS BYTE:

The user has the option of polling the printer for mode status. This is accomplished by sending the printer the control code

M_REQ 15H. The printer will then transmit back to the host the following one byte status indicating the current print modes:

BIT WEIGHT DESCRIPTION

0 Landscape Print ON = 1 1 Double Wide ON = 1 2 Not used 3 Double High ON = 1 4 2 of 5 Bar-code ON = 1 5 Not used (always = 0) 6 Not used (always = 0) 7 Condensed Print ON = 1

8). PAPER CUTTER FEATURES:

• The SP-327 is equipped with a long life guillotine paper cutter that is user activated via the escape code ESC c.

• The printer controller board monitors the paper cutter's home switch. If the cutter blade is not on the home position

(example: due to tampering), then the controller card will energize the cutter and home the guillotine blade.

• When the cutter is energized, an internal watch timer is set for 1 second. If the cutter blade does not reach the home

position within this allotted time the controller board will set bit 2 of the STATUS byte to a logic one indicating a cutter jam has occurred. The same condition will occur if the cutter blade overshoots the home position.

• Also provided is a solid state thermal overload circuit for the cutter (this is to protect the cutter motor from a locked

rotor or micro processor malfunction).

• The paper cutter's MTBF( mean time between failure) is 400,000 cuts .The MTBF may be severely shortened if

TELPAR paper is not used. Contact TELPAR for replacement paper (see section 15 on page 7 for the part number for replacement Telpar paper for the SP-327).

11). SELF TEST MODE:

The SP-327 has a self test mode that will print and cut a sample ticket utilizing all of its control code features. The printer

does NOT have to be connected to the host via the serial port to print a Self Test ticket.

NOTE: The printer’s Power / Feed Switch has three valid positions of operation: OFF, ON (middle position), and

PAPER FEED (the Paper Feed position is temporary – the switch should spring back into the ON position whenever the

switch is released from the Paper Feed position).

To placethe unit into self test mode, first turn the power switch to the off position. Next, push the power switch all the way over to the Paper Feed position. Release the switch after one second, and a self test sample will be printed and cut. All electrical/mechanical portions of the printer are exercised and checked bythis action.

SP-327 Thermal Printer Maintenance Manual

Introduction

The SP-327 printers are designed to require a minimum of maintenance and service. This section provides basic instructions for general care, maintenance and cleaning of the thermal print mechanism.

Electrical and mechanical repairs should be performed by qualified personnel only. Make certain that all electrical connections are disconnected before any service is performed on the SP-327 printers. Personnel involved in repair and maintenance of the print mechanism, or other electronic components should take appropriate measuresto guard against electrostatic discharge. Electrostatic discharge can damage the heating elements and ICs associated with the printer.

.. Required Tools and Supplies 1. Common hand tools 2. Short bristle brush 3. Denatured alcohol 4. Cleaning rags 5. Cotton swabs

6. Low temperature grease

General Care and Handing To ensure high print quality and long print head life, always use thermal paper approved by TELPAR Corporation.

Do not operate the printer without paperinstalled in the mechanism. Operation without paper may cause damageto the thermal print head. When the printer is not in use, it is recommended that the paper release lever be switched to the release position. This will prevent deformation of the soft print platen from constant spring pressure.

In applications were prolonged dense printing is performed, condensation may occur. This condition occurs when the thermal print head is heated to the point where is releases water vapor contained within the paper. Condensation can also appear when printing in extreme low temperatures, or in high humidity environments. Excessive condensation can cause the paper to stick in the mechanism and cause a jam condition.

Removing Paper from the Mechanism Excess paper that remains in the print mechanism may be easily removed before cleaning. Paper can be removed

by turning the motor in the reverse direction by hand. Tweezers may be used to remove remaining paper lodged in the mechanism. Caution should be excised when removing paper with any tool. The surface of the thermal print head is made of a ceramic material that can be easily damaged. A cotton swab is recommended for removal of paper dust in this area.

Cleaning

Print quality will deteriorate if paper particles or thermal sensitive residues build on the heating elements of the thermal print head. To clean the mechanism and print elements, follow the procedure below.

1. Push outward (left and right) on the cutter retaining tabs and flip the cutter assembly forward out of the

way.

2. Once the cutter is out of the way, locate the two upper front cover retaining screws and remove them from the

assembly.

3. Flip the front of the print mechanism forward to gain access to the printer platen and thermal print

elements. .

4. Remove the print platen from the mechanism carriage (note proper orientation of platen and paper

release cam lever position)

5. Once the platen has been removed, the thermal print elements will be visible. The print head may be

cleaned with a cotton swab moistened with alcohol. Do not use an abrasive cleanser, paper or shop cloth to clean the print head as damage may occur to the heating elements.

6. The print head assembly may be reassembled in the reverse order once the alcohol has been dried

completely.

7. Make certain that cluster gears are free from excessive dust or paper particles. The cluster gears

may be cleaned with compressed air, or with a short bristle brush.

Once the mechanism is reassembled, a test print is recommended. The SP-327 exterior may be cleaned with a non-abrasive cleanser. Care should be taken to prevent liquids from entering inside the electrical sub-assemblies.

Cutter Assembly

Prior to any type of service or maintenance to the cutter mechanism, disconnect all power to the printer.

Caution must be observed when service cleaning is being performed on the cutter assembly. Cutter blades are sharp and may cause serious injury. The cutter assembly can be cleaned with alcohol and cotton swabs. Moisten a cotton swab to clean the blade and associated mechanical components. Once the cutter assembly has been cleaned, wipe off excess solvent. Low temperature grease may be applied to the cutter as shown below.
