Notes on using the cutter
(1) Note also that the paper length used per transaction must be at least
15mm.
(2) The maximum number of successive cuts by the cutter is 30 cuts per
minute (at least two seconds per cut). Using the cutter at a higher rate may
cause a failure.
(3) Do not pull the paper during cutting. Doing so may cause a paper jam or
another problem.
(4) Each time that 30 sheets of paper are printed, the paper must be removed.
Otherwise, the printed paper remains in the automatic cutter section and may
cause a cutting error.
Notes on printing of barcodes and two-dimensional codes
(1) Barcodes that are rotated 90 degrees or aligned vertically when printed may
not be readable. Verify the readability in advance.
(2) Printouts on label paper or thick paper may contain blurs, depending on
humidity and other environmental conditions. Adjust the print speed and
print density appropriate for the type of paper used, and verify the
readability in advance.
(See Examples (1) and (2) in Section 10-2, "Setting Up the Printer.")
(3) The recognition ratio of two-dimensional codes (QR codes, PDF417,
DataMatrix, MaxiCode and RSS) varies depending on various factors,
including the module width, print density, ambient temperature, thermal
roll paper type, and reader performance. Adjust the print speed and print
density appropriate to printing two-dimensional codes, and verify the
readability in advance.
(See Examples (1) and (2) in Section 10-2, "Setting Up the Printer.")
(4) The paper transport accuracy may be negatively affected by printing a
barcode in the Upper margin at the beginning of paper transport or in the
Lower margin at the end of paper transport. Verify the readability before
starting printing.
