I have Monroe 4130 calculator and even with new print ribbon it is very faint

The hammer, ot the actuator will be defect. Replace the whole machine.

Could it be you are using old ribbons? Are you using the correct ribbons?
did you put in the ribbon correct and is the ribbon transported, while it is printing, or is it stuck in the calculator. Just some questions to check out.

It may be time for a new ink ribbon.

While in the D position or PD position, N Count
is OFF. In the N Count N position every
Plus, Minus, Equals Plus, Equals Minus,
Memory Plus or Memory Minus key depression
is counted. The Accumulator and its N Count
or the GT N Count can be printed by
depression of the Subtotal or Total key. When
either Memory Subtotal or Memory Total is
depressed, Memory N Count will print. N Count
is always printed in red, left justified. If the
Equals key is depressed immediately after the
Subtotal Total, Memory Subtotal, or Memory
Total the average of the entries is printed.
When the N Count prints on the 7150, an audit
symbol will print to the left of the N Count.
The audit NA will identify the Accumulator
register N Count, NG will identify the GT
register N Count and NM will identify the
Memory N Count.

Hi,
You need a new ribbon.
Older or much older desk top calculators used a small sized ribbon such as the old typewriters used except that the reels were about 1 inch across. Often they were divided into a red and black side.
It the calculator had all of the numbers strike the paper at the same instant, then it would use an
ribbon.
Here is a link to an Amazon.com page that sells the correct ribbon for your calculator.

Hope this helps,
Best Regards,

This is most likely a ribbon impact system. Any office supply store should have the ribbon you need, with information on compaitability on the package.

Remove the paper roll and gently but firmly pry on the bezel surrounding the paper exit path. Examine the sides of the ribbon casing for any clips or fasteners.
