Cutter Related Precautions; Barcode/2D Code Printing Precautions - Oki PT330 Guia Del Usuario

(8) If the paper has been left in the printer for a long time, it may deform and
cause faint printing. Therefore, if the paper has been left for a long time,
feed the paper forward by 20-30mm before printing.
(9) If non-recommended paper is used, print quality and/or the thermal head
life cannot be guaranteed. In particular, use of paper containing "Na+, K+,
or Cl-" may significantly shorten the life span of the thermal head.
(10) Using a non-recommended AC adapter may cause blurred and/or uneven
printing, so use only the recommended adapter.
(11) The paper may get marked during paper changing or when the top cover
is shut, so feed the paper forward by 20-30mm before printing.

13-2. Cutter Related Precautions

(1) Do not use the cutter continuously at a rate exceeding 10 cuts per minute
(1 cut per 6 seconds or more). Excessive use may cause a malfunction.
(2) Do not remove paper while it is still being cut. Doing so may cause
problems such as a paper jam.
(3) If the top margin is set at 3mm, be sure to remove the printed paper each
time the printing and cutting operation is completed as roll back of the
printer paper takes place before printing. Not doing so may cause problems
such as a paper jam.

13-3. Barcode/2D Code Printing Precautions

(1) When using thick paper, the printing speed and density should be adjusted
and readability should also be checked before using the printer as thick
paper may cause blurring depending on the usage environment and the
humidity.
(Refer to 9 Special Mode: 9-2. Changing the Setup.)
(2) For 2D codes, adjust the printing speed and density to obtain a good
recognition rate. As readability varies depending on the module width,
print density, ambient temperature, type of thermal roll paper, and reader
performance, check this before using the printer.
