Panasonic copier supplies sit under the FQ prefix, and the third letter tells you what the part is. FQT numbers such as FQTK20, FQTF15 and FQTA30 are toner, while FQZ numbers including FQZK20 and FQZA25 cover developer and related units. Many Panasonic copiers expect the developer to be changed at intervals alongside the toner rather than left in place.
Matching FQ Numbers to Your Copier
The FQ code is printed on the toner bottle and on the developer pack, and it is the only dependable way to order because a single copier family can span several supply revisions. If you are replacing developer for the first time, note the code before removing the old unit.
