Abstract
Adjusting emulated encoder frequencies in an example embodiment can include determining a difference between an encoder count and a theoretical encoder count and adjusting a frequency of an emulated encoder signal to mitigate at least some of the difference between the encoder count and the theoretical encoder count.
Claims15
A system, comprising:
- a determine engine to determine a difference between an encoder count and a theoretical encoder count;
- an adjust engine to adjust a frequency of an emulated encoder signal to mitigate at least some of the difference between the encoder count and the theoretical encoder count;
- and
- a generate engine to generate the emulated encoder signal at the adjusted frequency.

A non-transitory computer readable medium storing instructions executable by a processing resource to cause a device to:
- count, via a counter, a total number of ticks generated by an encoder during a time interval between consecutive top of form (TOF) marks on media passing by a sensor included in the encoder;
- determine a difference between the encoder count and a theoretical encoder count;
- adjust a frequency of an emulated encoder signal to mitigate at least some of the difference between the encoder count and the theoretical encoder count;
- and
- generate the emulated encoder signal, via an encoder signal emulator, at the adjusted frequency.

A method, comprising:
- sensing, via a sensor, invisible marks and top of form (TOF) marks on media during continuous printing of a print job on the media;
- calculating a frequency of an emulated encoder signal from a speed of the media based on the sensed invisible marks;
- counting, via a counter, a total number of ticks generated by an encoder during a time interval between sensing consecutive TOF marks;
- determining a difference between a value of the encoder count and a value of theoretical encoder count;
- and
- adjusting the frequency of the emulated encoder signal to mitigate at least some of the difference between the value of encoder count and the value of theoretical encoder count.
