6. For the CL408e, some the characters in label are printed smaller than normal. You should:

Check data packets

Check the I-mark sensor level

Heck the voltage going to the print head

Check the timing belt tension 　　

Mostly like the tension in the belt from the stepper motor to the platen roller is off. This will cause the paper to feed unevenly from time to time, especially when it is feed backwards.. This will then lead to characters to be of a different size than intended.

12. The tags from the TG3 do not stack up orderly. This may be due to:

Stacker's conveyer belt is worn

Too much energy applied during printing

Print speed set to maximum

Over time the convey belt will wear down and lose its grip on the tags, especially slicker ones.

Explanation

Over time the convey belt will wear down and lose its grip on the tags, especially slicker ones.

13. The CT424i keeps printing every other label. This might be because

The label size is set too big in the printer driver

It is cheaper to print a label

It can print on more types of materials

It can print in color

To avoid security risks by not using ribbons

Direct Thermal printers are cheaper and to a certain extend safer because they don't use ribbons. Both types can print in color, and that leaves B as the correct answer.

The barcode printed by the head is not readable

A wire is lose and the head is not grounded

One of the filaments inside the head shorted out

The head has past its expected life span

The print head checks the heating filament in the head, thus if one of heating elements goes bad the print head check display NG.

40. When measuring friction for the ribbon rollers it is good practice to:

Pull the gauge at an angle towards you

Pull the gauge very quickly

Pull the gauge at even speed

Pull in parallel with the ground

Typically the gauge should be held perpendicular to the printer and pulled straight up. Pulling the gauge at a slight angle away from the printer will cause the gauge to give a number that is (albeit slightly) not accurate.

41. The M84Pro show paper end error, but there is still label left. First thing you should try is:

Download new firmware into the printer

Replace the paper end sensor

Check the sensor levels

Ask the user to use a different liner. 　

It is quite possible that the paper end sensor is not set to the correct level when there is no label present. So you should check this first, before going ahead and replacing the sensor. In some rare cases the opacity of the liner can fool the sensor, but this can also be remedy by adjusting the sensor level.

42. When printing documents from MB400i with WLAN interface, the document fails at the print spooler. This is probably not because:

Encryption setting is incorrect

Gateway and net mask setting is incorrect

Signal strength is too weak

The printer is set to the wrong channel

The printer can fail to transmit to the printer spooler for a host of reason including settings that do no match and signal strength. However, being on a different channel is not a problem

45. On the CT408i the Headcheck(BARCODE) shows OK, but the customer cannot read the printed Matrix 2 of 5 barcode. Why?

The setting doesn't work for graphic barcodes

Headcheck(Barcode) checks everything but the barcode area

The all clear function was not used

Matrix 2of5 is an 2D and only 1D barcodes are valid

Headcheck(BARCODE) only works for limited set of barcodes (commands ESC+B, ESC+D, ESC_BD) and does not work for any barcodes in graphic format.

Replace the entire cutter unit

Check the timing belt tension in cutter

When the timing belt tension of the cutter is not right, the cutter blade itself cannot properly return to its start position. The blade occasional get in the way of the tag

Explanation

When the timing belt tension of the cutter is not right, the cutter blade itself cannot properly return to its start position. The blade occasional get in the way of the tag

51. The HT200e is accidentally turned off in the middle of downloading the firmware. You rebooted the printer but it will not download the firmware.

Turn the machine back on and try again.

Probably the PCB is damaged, replace the PCB then try again.

First clear the memory then download the new firmware.

Reboot the PC, clear the printer's memory, and try again.

Powering down the printer in the middle of a firmware download is highly unrecommended. It can damage the PCB and make it impossible to download firmware into the PCB again. If you are lucky you can just do an all clear and start again.
