victory over the HP Laserjet 2015n formatter card issue.
You could google specific instructions like I did, but essentially I reflowed the solder by baking the formatter card in a 200C oven for five minutes. Allow to cool for 15 minutes, then replace in printer.
Thanks to my now-working printer, I've printed test prints, high school applications, recipes and newly-composed medleys.
I'd call this repair a success. Now, off to boast about it at the Daye Jobbe. They'll be suitably impressed.
Her Grace, while fully supportive of paper-free offices, still has a need for a printer from time to time.
