H4-01 Heat roller low temp is correct.
You machine has a fuser unit that it uses to bond the toner to the paper, it does this with a heater lamp heating a set of rollers that the paper passes threw after it has printed.
Your machine monitors this unit to regelate its temp, your machine is sensing via a thermister and thermal fuse the temp of the fuser unit is not hot enough to enable use, this would mean the heater lamp is blown, thermister is faulty or thermal fuse blown 95% chance it's the lamp,
What one normally does is replace fuser assembly with new this is not a user thing it requires a tec, but if your into it, it is the hi voltage hot bit near paper exit.

SOURCE: I have a H5-01
H5-01 means that the paper sensor in the fusing unit is defective and needs to be replaced. If you open the machine and clean the entire area around the fuser unit sometimes that will clear the error as well.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
