NOTES: 1. Notes on using the Epson PS-180 power supply unit

If the printing is continuously performed with the high print ratio, the overcurrent limitation might be operated. Therefore, the printing length must not exceed the following values when printing with high print ration.

Print ratio: Number of dots being energized per one dotline / Total number of dots per one dotline (512 dots)

If the overcurrent limitation is operated when printing is continuously performed with a high print ratio, uneven print density or a low voltage error may occur.

2.Notes on using the power supply unit other than the Epson specified one (PS-180)

The current consumption of this printer is as shown in Figure 1.9.1. User must consider these values when the user provides the power supply unit other than the Epson specified one.

Note that the current consumption may increase if the printer is used in a low temperature or the print density is set to “dark”.

The power supply unit with a small power capacity may not operate the printer correctly.

Contact Epson if you need more detailed information.
