I'm afraid that for reasons that have yet to emerge, freestanding CD recorders have an abysmal reliability record compared with apparently similar computer drives.
I have 3 different Philips and Sony recorders and each has reached me because previous owners had problems and gave up to use computers to record instead. Another 2 Philips decks were dead when found in a dumpster and a flea market.
I can only suggest you try different brands of CDR. My Philips decks don't work reliably with Verbatim discs but the Sony does.
I presume this machine requires so-called Audio CDR -- which limits the choice a bit. Frankly these discs are a swindle -- costing 5 times the price of data discs simply because they have a bit of code written onto them that permits the recorder to work.
On two of my machines I have butchered the hardware to permit the use of data discs.
My advice is if you can't get your recorder to work reliably use the CD/DVD writer in your computer -- you just need a program like Audacity and a cable to link a cassette deck to the line-in input of the computer's sound circuitry.
