Ink not drying fast enough

[gabagoo]

Hi Guys, I have a jv150 for the last 2 or 3 years...upgraded from my jv130spll.
In the older printer my heat settings were about 45 pre and 40 print...the new printer's profiles (from Flexi) had much higher heat settings and basically from about a week in I lowered them with good results. Lately though I am running into far too many issues with dark colours not drying by the time they reach the take up reel. Mostly on retractable banner material, wherby it leaves a mottled image and the ink has transferred to the back side of the banner material. I run a fan in front of the printer to help dry any prints that are latched up and I suppose it works, but not all the time.
Do you think it is the heat settings?

Curious what others with this unit run their heat at?

Why don't you try various settings on various medias ?? After three years, some things could easily have changed/aged.

experiment with upping heat settings or even checking out a different color profile.

I usually crank the post heater up as high as it will go. It won't make the media buckle once it's off the center platen.

Yea I suppose. I will try and increase post heat...but weird that what worked 6 months ago now is troublesome.

Maybe the humidity in the room has gone up? I know here in Denver it can spike really fast when it rains because it's so dry here all the time.

Could be due to aging of the machine, could be a bad batch of ink.

Also, as you're in North America, make sure that the Voltage Selector switch on the side of the machine is set to "120V". If it's set to 220V then the machine will struggle to ever get up to the temperature requested (FYI, the electronics of the machine are self-switching to whatever voltage you plug into, but the heater voltage is set manually by this switch.
