UBI EasyCoder 501 – Technical Manual
Provided the printer is fitted with a thermal transfer ribbon mecha-
nism, you may choose printing method at will.
❑ Set up the printer for the correct paper or ribbon type in the Setup
Mode (Service\Print Defs\Paper Type).
For setup instructions, please refer to the chapters “Setting up
EasyCoder 501” and “Setting up EasyCoder 501 E & 501 SA”
earlier in this manual.
Since direct thermal printing requires more heat that thermal
transfer printing, there is a safeguard against incorrect setup:
• If the printer is loaded with thermal transfer ribbon but set up
for direct thermal printing, error condition 1058 “Transfer
ribbon fitted” will occur at printing.
• If the printer is not loaded with thermal transfer ribbon but set
up for thermal transfer printing, error condition 1027 “Out of
transfer ribbon” will occur at printing.
❑ Adjust the printhead pressure. Direct thermal printing requires
more pressure than thermal transfer printing. Do not use more
pressure than necessary, since it may reduce the life of the
printhead and – in case of thermal transfer printing – cause
ribbon wrinkling. Please refer to chapter “Printing Adjust-
ments” on next page.
❑ Load a supply of direct thermal paper only, or thermal transfer
ribbon plus a suitable face material. Please refer to the Operator's
Guide or User's Manual for loading instructions.
❑ Print a few labels, preferably test labels (see chapter “Setup
Parameters, Print Defines” earlier in this manual) and check
that the printing is distinct and even across the label web. If not,
readjust the printhead pressure (see next page).
❑ In case of thermal transfer printing, check that the ribbon does
not become wrinkled. Else, adjust the ribbon guide plate as
described in next chapter.
❑ In case of peel-off operation, check that the backing paper is tight
and flat after it has passed the dispenser edge. If not, adjust the
dispenser edge.
