Cable routing

To prevent the printer from becoming unplugged accidentally, make sure the cables are routed as shown in the illustration below.

For USB printers only:

Guide the USB cable through the strain relief and out the slot in the connector cover, as shown in the illustration. The USB cable ﬁts underneath the power supply and cash drawer cables. The RS-232C cable routes straight out the back when attached.

Test the printer

If the printer is functioning normally, it will beep once. If it responds differently, look in Chapter 4: Using the Printer, “Troubleshooting the printer” (page 31) or contact TPG for technical support.

The printer will arrive for installation pre-conﬁgured. The printer’s current conﬁguration appears on the test (diagnostics) printout. However, if you would like to run a new print test or check the conﬁgurations, you can run a diagnostics printout detailing the current conﬁguration.

To run a diagnostic test:

1 Make sure paper is in the printer (1).

2 Open the receipt cover (2).

3 Press and hold the paper feed button (3).

4 Close the receipt cover, continually holding the paper

feed button until the conﬁguration printout begins (4).

For further instructions, see Chapter 4: Using the printer, “Conﬁguring the printer” (page 20).

Page 20

Chapter 4: Using the Printer20

Chapter 4: Using the Printer

Conguring the printer

The conﬁguration menu allows the user to set general printer parameters. The test prints the diagnostics form, which details settings for all functions. The printer will partially cut the paper between each variation.

The printouts may vary for each model. The test ends with a partial cut of the paper. A complete test printout may require the use of several feet of paper.

Since the printer is usually shipped pre-conﬁgured, most users do not need to change the conﬁguration of the printer. If you make adjustments to the conﬁguration, be careful not to inadvertently change settings that may affect the printer’s performance. TPG does not recommend that users change the printer conﬁguration.

Additional information on conﬁguring the printer is found in the A798 Programming Guide.

Hint: The printer is shipped with a test printout that includes the preset conﬁguration. If you run into problems after changing the printer conﬁguration, use these settings as a default. For guidance or assistance, you may contact an TPG representative.

Monochrome paper print density

This function makes it possible to adjust the energy level of the printhead to darken the printout or adjust for paper variations. An adjustment should only be made when necessary. The factory setting is 100%.

Warning: Choose an energy level no higher than necessary to achieve a dark printout.Failure to observe this rule may

result in a printer service call or voiding of the printer warranty. Running at a higher energy level will reduce the printhead life. Consult your TPG representative or TPG technical support if you have any questions.

When the printer prints high-density print lines (text or graphics), it automatically slows down.

To change the print density:

1 Enter the conﬁguration menu (follow directions on page 21).

2 Select “Set Hardware Options” from the main menu.

Printer responds, “Hardware Options Menu,” and when scrolled prompts, “Set Print Density?”

3 Select “Yes”.

A warning is printed, followed by the density adjustment selections.

Enter clicks for selection, then hold button down at least 1 second to validate.

Chapter 4: Using the Printer24

When to change the receipt paper

Change the paper when it is near the end of the roll or out. When the paper is low, you will want to monitor usage to avoid running out part way through a transaction. When the paper is out, you must load a new roll immediately or data may be

lost!

When paper is low:

• Colored stripe appears on the receipt paper, (if paper is purchased with stripe) and indicates enough paper remains for a small transaction.

• If paper low option is installed on the printer, the green LED ﬂashes slowly indicating that approximately 15 feet of paper remains. If too much paper is left on the roll, the “paper low” setting can be adjusted by entering the conﬁguration menu and changing the “paper low” extension setting.

When paper is out:

• Green LED ﬂashes quickly indicating the paper must be installed.

Warning: Do not try to operate the printer or host computer if the printer runs out of paper. The printer may continue to

accept data from the host computer even though it is unable to print. Data may be lost as a result!

For instructions on how to change the receipt paper, look in Chapter 3: Setting up the Printer, “Load or change the receipt paper” (see page 12).

Printhead Setting

The printhead energy rating and printer setting must match. The setting will be preconﬁgured from the factory but may require changing should service to the thermal mechanism be required. The “Head Setting” on the diagnostic printout must match the letter marked on the front right of the thermal mechanism. Whenever the thermal mechanism is replaced, if the letter on the the mechanism is different from the head setting, you must enter the conﬁguration menu and set the printhead to match. (See A798 Service Guide for replacing the thermal mechanism.)

Chapter 4: Using the Printer 25

Preventing overheating of the printhead

There are restrictions on the duty cycle because of the heat generated by the thermal printhead when printing solid blocks (regardless of the length of the block in relation to the print line). The restrictions are ambient temperature, the percentage of time (measured against one minute) of continuous solid printing, and the amount of coverage.

Keep in mind that the ambient temperature may be affected by factors such as direct exposure to sun or close proximity to heating elements.

Caution: When the duty cycle exceeds the limits shown in the table, the receipt printhead will heat up and shut down. This

may damage the printhead.

To avoid this problem, do one or a combination of the following:

1 Reduce the amount of coverage.

2 Reduce the time of continuous solid printing.

3 Reduce the ambient temperature.

Allowable duty cycle (measured over one minute of continuous printing)

Amount of solid coverage Ambient temperature

25°C 35° C 50° C

20% 100% 50% 20%

40% 50% 25% 10%

100% 20% 10% 4%

Duty cycle

Percentage of time that the specied “Amount of solid coverage” can be printed during a one minute period of time.

Example: at 20% solid coverage,

35° C temperature, a 50% duty cycle is to be used, resulting in 30 seconds of printing and 30 seconds without printing.

For reference:

• A typical receipt with text (contains some blank spaces) is approximately 12% dot coverage.

• A full line of text characters (every cell on the line has a character in it) is approximately 25% dot coverage.

• Graphics are approximately 40% dot coverage.

• Barcodes are approximately 50% dot coverage.

• A solid black line is 100% dot coverage.
